Usually, sets are represented in curly braces {}, for example, A = {1,2,3,4} is a set. The settheory defines the different types of sets, symbols and operations performed. Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. In essence, the power set of a set is the collection of all its improper and proper subsets. Find Cartesian product $\color{blue}{\left( A \times B \right)}$ of sets $A = \{1, 2, 3\}$ and $B = \{x, y\}$. Yup, you read that right: each of these sets has the same number of elements. Sometimes we may be interested in the cardinality of the union or intersection of sets, but not know the actual elements of each set. In particular: We say that a set that contains some elements of another set (and none others) is the latter's subset. And if you'd like to list its elements, you can do it the usual way inside curly brackets {}. From the given data, we know that there are 3 students in region \(e\) and 7 students in region \(h\), since 7 students were taking a \(S S\) and \(N S\) course, we know that \(n(d)+n(e)=7\). What are the area of a regular polygon formulas? Add text here.Fifty students were surveyed, and asked if they were taking a social science (SS), humanities (HM) or a natural science (NS) course the next quarter. An entity is an abstraction from the complexities of a domain. An entityrelationship model (or ER model) describes interrelated things of interest in a specific domain of knowledge. On the other hand, the one with all four toppings. If you'd like to learn more, make sure to read about cardinal numbers. It also provides the cardinality of the power set. Power-Set Definition, Formulas, Calculator. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Entity-relationship diagrams (ERDs) don't show single entities or single instances of relations. Starting with the intersection of all three circles, we work our way out. The lines, arrows and crow's-feet of some diagrams owes more to the earlier Bachman diagrams than to Chen's relationship diagrams. Carte, Traci A.; Jasperson, Jon (Sean); and Cornelius, Mark E. (2020) "Integrating ERD and UML Concepts When Teaching Data Modeling," Journal of Information Systems Education: Vol. Some commonly used sets are as follows: The order of a set defines the number of elements a set is having. ", Elmasri, Navathe: "The ER model concepts are designed to be closer to the users perception of data and are not meant to describe the way in which data will be stored in the computer. However, an online Interval Notation Calculator helps you to find the interval values from the given set interval notation. Legal. The elements that are written in the set can be in any order but cannot be repeated. Welcome to MathPortal. (Yes.). Put your understanding of this concept to test by answering a few MCQs. An entity may be a physical object such as a house or a car (they exist physically), an event such as a house sale or a car service, or a concept such as a customer transaction or order (they exist logicallyas a concept). How does its subset A B look? We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. In sets theory, you will learn about sets and its properties. This calculator will help you make the most delicious choice when ordering pizza. Write the given statement in three methods of representation of a set: The set of all integers that lies between -1 and 5. 2.How many subsets are there altogether? All entities except weak entities must have a minimal set of uniquely identifying attributes which may be used as a unique/primary key. I appreciate the way of note presentation . Randomly change the order of elements in a set. Check out 37 similar algebra calculators , Sets and subsets: notation and definition, the fundamental counting principle calculator, The cardinality of the power set (i.e., the number of its elements). For a set of natural numbers, we can do one-to-one mapping of the resulted set, P(S), with the real numbers. ERROL's semantics and implementation are based on reshaped relational algebra (RRA), a relational algebra that is adapted to the entityrelationship model and captures its linguistic aspect. Note that, as such, it is not empty. All the set elements are represented in small letter in case of alphabets. What's the surface area of a cone formula? The two sets A and B are said to be disjoint if the set does not contain any common element. Three symbols are used to represent cardinality: These symbols are used in pairs to represent the four types of cardinality that an entity may have in a relationship. Indefinite article before noun starting with "the". If the set has n elements, then its power set will hold 2n elements. In this example, we paste a set of primes less than 100 in the input box and we want to find how many primes there are in this interval. How many people drink neither tea or coffee? then count only the duplicate I always use your sites for my maths problem, Am got so much help from this website Now, it's time to go back to finite sets and how to calculate their cardinality. If you love our tools, then we love you, too! From the above relationship we can calculate |2s| as follows: This is the relationship between a power-set and the binomial theorem. Did you face any problem, tell us! Do peer-reviewers ignore details in complicated mathematical computations and theorems? Physical view show how data is actually stored. As the above subset notation suggests, A can contain all the elements of B (i.e., be the same as B) and still be called a subset. Setting up a list of them all may be time-consuming in itself, but counting them (i.e., determining the cardinality of a power set) is very simple. For example, if set A = {1, 2, 3, 4} and set B = {1, 3, 4}, then set A is the superset of B. However, before we reveal the answer, let's go through the power set example ourselves. Welcome to Omni's power set calculator, where we'll deal with sets and their subsets (what is a subset). Sets, in mathematics, are an organized collection of objects and can be represented in set-builder form or roster form. The cardinality of a set is denoted by vertical bars, We provide top-quality homework help to students of all levels. Knowing the size of a data set is also important when It will also generate a step by step explanation for each operation. A set A is said to be a subset of B if every element of A is also an element of B, denoted as A B. For instance, the set A = {1, 2, 4} A = \{1,2,4\} A = {1, 2, 4} has a cardinality of 3 3 3 for the three elements that are in it. Quickly apply the set union operation on two or more sets. Example: A set of natural numbers up to 10. And if we think a bit, it also works for other finite sets: after all, there are as many 1-element subsets as elements of the underlying one. Cardinality of sets A special and simple aspect of sets that mathematicians are always interested in, is the total number of distinct elements of a set whether it is a finite set or infinite. In statement form, it can be written as {even numbers less than 15}. Then the Press the calculate button for sets and subsets. Quickly find the number of elements in a set. Setabulous! To calculate the total number of sets present in a power set we have to use the formula: An empty set is a null set, which does not have any elements present in it. Some ER model notations include symbols to show super-sub-type relationships and mutual exclusion between relationships; some don't. Set A is said to be the superset of B if all the elements of set B are the elements of set A. This includes students from regions \(a, b, d,\) and \(e .\) since we know the number of students in all but region \(a,\) we can determine that \(21-6-4-3=8\) students are in region \(a\). Entities can be thought of as nouns. And again, always getting something strictly larger. Click Start Quiz to begin! Why is sending so few tanks Ukraine considered significant. This millionaire calculator will help you determine how long it will take for you to reach a 7-figure saving or any financial goal you have. Once you've checked that this is a bijection, then you'll see the sets have the same cardinality. Chen proposed the following guiding rules for mapping natural language descriptions into ER diagrams: "English, Chinese and ER diagrams" by Peter Chen. An entity, strictly speaking, is an instance of a given entity-type. If Set S = { }, then P(S) = { { } } is returned. Your Mobile number and Email id will not be published. ", In Feinerer it says "Problems arise if we operate under the look-across semantics as used for UML associations. Your Mobile number and Email id will not be published. The number of elements in a power set of X is 2. Example: If A = {1,2,3} and B {2,3,4,5}, then universal set here will be: In set theory,the operations of the sets are carried when two or more sets combine to form a single set under some of the given conditions. Note that sometimes, both of these phases are referred to as "physical design. Example: Set A = {1,2,3} and B = {4,5,6}, then A intersection B is: Since A and B do not have any elements in common, so their intersection will give null set. As mentioned in 4., it certainly works for empty sets (1 is larger than 0). And we can take the power set of the result. It is denoted by A B. From the source of Wikipedia: Power set, subsets as functions, Relation to binomial theorem, Recursive definition, Subsets of limited cardinality, Power object. That infinity is different. Also, to adapt the program to the non-standard set format that uses square brackets and semicolons, we put a semicolon in the set element delimiter field and square brackets in the fields for left and right set symbols. If A has n elements then the formula to find the number of subsets of a set in a power set is given by: So, the number of subsets in a power set of A will be: Subsets of A = {}, {1}, {2}, {3}, {1,2}, {2,3}, {1,3}, {1,2,3,}, Hence, P(A) is {{}, {1}, {2}, {3}, {1,2}, {2,3}, {1,3}, {1,2,3,}}. Provide data numbers and the calculator will calculate the power sets, cardinality, subset, and proper subsets for them. There, we see a section for the elements of our set, so we input them one by one from the top. Or any integers. It also represents the cardinality of the power set. Since a set is usually represented by the capital letter. A power set is set of all subsets, empty set and the original set itself. This browser-based program finds the cardinality of the given finite set. Find its cardinality. However, Computers not currently assigned to a Room (because they are under repair or somewhere else) are not shown on the list. a plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates, which are the signed Select the correct answer and click on the Finish buttonCheck your score and answers at the end of the quiz, Visit BYJUS for all Maths related queries and study materials, Your Mobile number and Email id will not be published. We can represent it in set-builder form, such as: Example: set A = {1,2,3} and set B = {Bat, Ball}, then; A B = {(1,Bat),(1,Ball),(2,Bat),(2,Ball),(3,Bat),(3,Ball)}. Elmasri, Ramez, B. Shamkant, Navathe, Fundamentals of Database Systems, third ed., Addison-Wesley, Menlo Park, CA, USA, 2000. Others model state changes separately, using state transition diagrams or some other, Many other kinds of diagram are drawn to model other aspects of systems, including the 14 diagram types offered by, Today, even where ER modeling could be useful, it is uncommon because many use tools that support similar kinds of model, notably class diagrams for OO programming and data models for relational, This page was last edited on 17 January 2023, at 05:35. Therefore, the cardinality of the given set P is 4, Cardinality of a Finite Set. Therefore, no. since the universal set contains \(100 \%\) of people and the cardinality of \(F \cup T=90 \%\), the cardinality of \((F \cup 7)^{c}\) must be the other \(10 \%\), The previous example illustrated two important properties, \(\mathrm{n}(A \cup B)=\mathrm{n}(A)+\mathrm{n}(B)-\mathrm{n}(A \cap B)\). Diagrams created to represent attributes as well as entities and relationships may be called entity-attribute-relationship diagrams, rather than entityrelationship models. A set which contains all the sets relevant to a certain condition is called the universal set. Remember that a function f is a bijection if the following condition are met: 1. The power set of a countable finite set is countable. Delete all unique elements from a set (leave duplicates). Therefore, according the power set calculator elements are 2^4 = 16, $${1, 2}, {1, 3}, {2, 3}, {1, 4}, {2, 4}, {3, 4}$$, $${1, 2, 3}, {1, 2, 4}, {1, 3, 4}, {2, 3, 4}$$. The input set in this example is a collection of simple math expressions in variables x and y. If you know the cardinality of sets, then you can compare them by size and determine which set is bigger. The null set is considered as a finite set, and its cardinality value is 0. The model's linguistic aspect described above is utilized in the declarative database query language ERROL, which mimics natural language constructs. In the case of the design of an information system that is based on a database, the conceptual data model is, at a later stage (usually called logical design), mapped to a logical data model, such as the relational model; this in turn is mapped to a physical model during physical design. The sets are represented in curly braces, {}. since we know there are 3 students in region 3 , there must be With this notation, relationships cannot have attributes. The cardinality of \(A \cup B\) is \(7,\) since \(A \cup B=\{1,2,3,4,5,6,8\},\) which contains 7 elements. If you really want to stress that A B but the sets are not equal, you can use A B. Free Powerset Calculator - Find the powerset for a given set step-by-step Books in which disembodied brains in blue fluid try to enslave humanity. WebFree Set Cardinality Calculator - Find the cardinality of a set step-by-step Is the cardinality of AxBxC different to that of Ax(BxC), since AxBxC gives a 3 tuple, but Ax(BxC) gives a two tuple? The cardinality of \(A \cap B\) is 3 , since \(A \cap B=\{2,4,6\}\), which contains 3 elements. G. Everest, "BASIC DATA STRUCTURE MODELS EXPLAINED WITH A COMMON EXAMPLE", in Computing Systems 1976, Proceedings Fifth Texas Conference on Computing Systems, Austin,TX, 1976 October 1819, pages 39-46. In a relational database a relationship between entities is implemented by storing the primary key of one entity as a pointer or "foreign key" in the table of another entity. A \cup B, A \cap B ?\). Cardinality constraints are expressed as follows: Attributes are often omitted as they can clutter up a diagram; other diagram techniques often list entity attributes within the rectangles drawn for entity sets. Relationships can be thought of as verbs, linking two or more nouns. [16] A set which contains a single element is called a singleton set. A set is a collection of elements or numbers or objects, represented within the curly brackets { }. How did adding new pages to a US passport use to work? Examples: a computer, an employee, a song, a mathematical theorem, etc. We begin with the formal power set definition. But, A = {2,5} is a subset of B = {2,5,7} and is a proper subset also. The order of set is also known as the, The sets are represented in curly braces, {}. WebThe size of a nite set (also known as its cardinality) is measured by the number of elements it contains. What is cardinality example? P(S) of set S, if operated with the union of sets, the intersection of sets and complement of sets, denotes the example of Boolean Algebra. If the given set has n elements, then its Power Set will contain 2n elements. You have already learned about the classification of sets here. It's time to go through a power set example, and we'll take the opportunity to show you how to use Omni's power set calculator for the task. If A is not a subset of B, then it is denoted as AB. Thus, A is the set and 1, 2, 3, 4, 5 are the elements of the set or members of the set. By the formula of power set, we know that, the number of sets we can form here is given by: where n is the number of elements of set A. Subsets of A = {}, {1}, {2}, {3}, {4}, {1, 2}, {1, 3}, {1, 4}, {2, 3}, {2, 4}, {3, 4},{1, 2, 3}, {1, 2, 4}, {1, 3, 4}, {2, 3, 4}, {1,2,3,4}. If $A = \{a, b, c, d \}$ and $B = \{c, d, e, f\}$, find $\color{blue}{A \cup B}$. The other cardinality counting mode "Count Only Duplicate Elements" does the opposite and counts only copies of elements. The cardinality of a set is denoted by vertical bars, like absolute value Solve Now If you look closely, you can see that some of the expressions are duplicated, which means that the input set is a multiset. In Chen's original paper he gives an example of a relationship and its roles. The Cartesian Product of two sets can be easily represented in the form of a matrix where both sets are on either axis, as shown in the image below. Each subset term can be written using binary expansion representation starting at 0 through 16 - 1 = 15. Cardinality of a set calculator Home > Algebra calculators > Set Theory - Cardinality of a set Method and examples Select Operation Cardinality of a set Solution Help Set Theory Here You It is denoted as A, If set A and set B are two sets then the cartesian product of set A and set B is a set of all ordered pairs (a,b), such that a is an element of A and b is an element of B. In a simple relational database implementation, each row of a table represents one instance of an entity type, and each field in a table represents an attribute type. How to make chocolate safe for Keidran? The cardinality of a set is a measure of a set's size, meaning the number of elements in the set.For instance, the set A = { 1 , 2 , 4 } A = \{1,2,4\} A={1,2,4} has a cardinality of 3 for the three elements that are in it. In set A, there are four elements and in set B also there are four elements. How many subsets of size 2 are there? Is the cardinality of AxBxC different to that of Ax(BxC), since AxBxC gives a 3 tuple, but Ax(BxC) gives a two tuple? To find how many different pizzas we can prepare, aka the number of subsets of {1, 2, 3, 4}, aka the cardinality of the power set of {1, 2, 3, 4}, we'll use the power set calculator. It can also be expressed in a verbal form, for example: one building may be divided into zero or more apartments, but one apartment can only be located in one building. The cardinality of the empty set is always zero. The cardinality is defined as the set size or the total number of elements in the set. Since empty sets contain no elements, hence they have a zero cardinality. This is shown below: Therefore, according to the above relation, the cardinality of the empty set will always be zero. Free Powerset Calculator - Find the powerset for a given set step-by-step Area integral calculator Factor to standard form calculator Find the illegal values of c in the multiplication statement These options will be used automatically if you select this example. If you want to contact me, probably have some questions, write me using the contact form or email me on The methods of representations of sets are: Statement Form: { I is the set of integers that lies between -1 and 5}, Set-builder Form: I = { x: x I, -1 < x < 5 }. Add elements to a set and make it bigger. Remember that counting the number of elements in a set amounts to forming a 1-1 correspondence between its elements and the numbers in f1;2;:::;ng. If set A and set B are two sets then the cartesian product of set A and set B is a set of all ordered pairs (a,b), such that a is an element of A and b is an element of B. elements in it. then count only the unique It also tells possible subsets of a certain function. We denote it by 2. There are 16 subsets. This type of model looks similar to a star schema, a type of model used in data warehouses. Entities and relationships can both have attributes. Here are a few examples, given to represent the elements of a set. Its value is greater than the original set. All conversions and calculations are done in your browser using JavaScript. It also provides the cardinality of the power set. State whether the following statement is true. Apply the set difference operation on sets A and B. Cardinality of a Set. Mathematics Computer Engineering MCA. Cardinality of a set S, denoted by |S|, is the number of elements of the set. The number is also referred as the cardinal number. If a set has an infinite number of elements, its cardinality is . Example | {1, 4, 3, 5}| = 4, | {1, 2, 3, 4, 5,.}| = . The first is the 'fan trap'. Let A be a set containing finite number of elements. If the input set is a multiset Set Cardinality Calculator - Symbolab Solutions Graphing Practice New Geometry Calculators Notebook Set Cardinality Calculator Find the cardinality of a set step-by-step full pad Examples There are three forms in which we can represent the sets. In mathematics, the power set is defined as the set of all subsets including the null set and the original set itself. See Entity-Relationship Modelling 2 for details. Please tell me how can I make this better. Everybody needs a calculator at some point, get the ease of calculating anything from the source of calculator-online.net. [17] And again. For example, the set of even numbers less than 15. Since the definition of cardinality says that two sets have the same cardinality if a bijection exists, this proves it has the cardinality of {1, 2, 3, 4, }. Once we have, we can add up all those regions, getting 91 people in the union of all three sets. If the number of elements is the same for two different sets, then they are called equivalent sets. A set is a collection of distinct elements. It is denoted by P(A). How many elements will be there in the power set of set A = {5, 6, 7, 8}. We use your browser's local storage to save tools' input. Let's look at the formal math set definition. Can I (an EU citizen) live in the US if I marry a US citizen? Find a partition of the natural numbers satisfying the following, Prove that the interval $ \ [0,2)$ and $ \ [5,6) \cup [7,8)$ have the same cardinality. Welcome to Omni's power set calculator, where we'll deal with sets and their subsets (what is a subset). First of all, enter the elements of the sets and ensure all the values are separated with a comma. Didn't find the tool you were looking for? In set theory, the power set (or power set) of a Set A is defined as the set of all subsets of the Set A including the Set itself and the null or empty set. Find the union $\color{blue}{A \cap B}$ of sets $A = \{ 5, 7, 3, 1\}$ and $B = \{2, 5, 9\}$. Split a set into a certain number of subsets. It is usually denoted by P. Power set is a type of sets, whose cardinality depends on the Let us go through the classification of sets here. In maths, we usually represent a group of numbers like a group of natural numbers, collection of rational numbers, etc. Power of a Set (P) Calculator. Find cardinality of a set For instance, the set A = {1, 2, 4} A = \{1,2,4\} A = {1, 2, 4} has a cardinality of 3 3 3 for the three elements that are in it. For any given set, the cardinality is defined as the number of elements in it. For example: {1,2,3,4} is a set of numbers. Now, enter set values and ensure all values are separated with a comma. Note that the conceptual-logical-physical hierarchy below is used in other kinds of specification, and is different from the three schema approach to software engineering. Correct nouns in this case are owner and possession. WebA set is represented by a capital letter. In mathematics, the cardinality of a set is a measure of the number of elements of the set. The set and subsets of a finite set are countable. How easy was it to use our calculator? It is an intensional model. In Roster form, all the elements of a set are listed. The set's size is denoted by the vertical bar characters, for example, |A| = 3 and |B| = 4. The power set is a set which includes all the subsets including the empty set and the original set itself. In statement form, the well-defined descriptions of a member of a set are written and enclosed in the curly brackets. I don't know if my step-son hates me, is scared of me, or likes me? = 1 * 2 * 3 * * n (learn more about in the factorial calculator). For example, {2,3,4} or {a,b,c} or {Bat, Ball, Wickets}. [15] The elements of sets are the numbers, objects, symbols, etc contained in a set. Q.2: How many elements are there for the power set of an empty set? We have several types of sets in Maths. Merge multiple sets together to form one large set. The "smallest" infinity is equal to the number of positive integers. In case of power set, the cardinality will be the list of number of subsets of a set. WebThis calculator is an online tool to find find union, intersection, difference and Cartesian product of two sets. The issue derives its name from the way the model looks when it's drawn in an entityrelationship diagram: the linked tables 'fan out' from the master table. For example, the set A = { 2, 4, 6 } {\displaystyle A=\{2,4,6\}} contains 3 elements, and therefore A Let $A= \{1,2,3,4,5,6,7,8,9,0,20,30,40,50\}$. The input set can be specified in the standard set format, using curly brace characters { } on the sides and a comma as the element separator (for example {1, 2, 3}) and in a non-standard set format (for example [1 2 3] or <1*2*3>). ER models are readily used to represent relational database structures (after Codd and Date) but not so often to represent other kinds of data structure (data warehouses, document stores etc.). The purpose of using sets is to represent the collection of relevant objects in a group. Therefore, the power set of an empty set { }, can be mentioned as; A recursive algorithm is used to generate the power set P(S) of any finite set S. This returns each of the set X in T that has the element x. ), Hubert Tardieu, Arnold Rochfeld and Ren Colletti La methode MERISE: Principes et outils (Paperback - 1983). Chen described look-across cardinalities. It describes the size of a set. Example: If A = {1,2,3,4} and B = {Red, Blue, Green, Black}. In the end, once you input all four numbers, you can read off the result from underneath, together with the list of all subsets separated by cardinality. Before we give the formula, let's try to understand it. For K-12 kids, teachers and parents. Total number of elements in power set = 2n, Here, n = 3 (number of elements in set Z), So, 23 = 8, which shows that there are eight elements of power set of Z, P(Z) = {{}, {2}, {7}, {9}, {2, 7}, {7, 9}, {2, 9}, {2, 7, 9}}. The best answers are voted up and rise to the top, Not the answer you're looking for? rev2023.1.17.43168. How many people have used neither Twitter or Facebook? If there are n elements in a set A, then the elements of power set are equal to 2^n, which will include all the subsets of A along with empty set and set A itself. The solution is to either adjust the model or the SQL. For further assistance, please Contact Us. This is called the cardinality of the set. The complement of any set, say P, is the set of all elements in the universal set that are not in set P. It is denoted by P. Another relation between Building and Computers is needed to capture all the computers in the building. Mathematics Stack Exchange is a question and answer site for people studying math at any level and professionals in related fields. And if you think you've had just about enough of the word "set," then better strap in because there's more to come until the count is settled. If set A and set B are two sets, then A intersection B is the set that contains only the common elements between set A and set B. The cardinal number of the set is 5. elements in it. Note: The set is also a subset of itself. {2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97}, [x; y; x + y; x + 1; y + 1; 2x; 2y; 2x + 1; 2y + 1; x; y; x + 1; y + 1; x + x; y + y; x + x + 1; y + y + 1; x; y + 1; 2y; x + 1; y + y; x + x + 1], --- ------------------- ---. The Cartesian Product is non-commutative: A B B A Example: A = {1, 2} , B = {a, b} Even the null set is considered to be the subset of another set. It is the smallest powerset and proper subset of every powerset. If you know the cardinality of sets, then you can compare them by size and determine which set is bigger. Another common extension to Chen's model is to "name" relationships and roles as verbs or phrases. It is the set of all possible values. The cardinality of the set \(A\) is often notated as \(|A|\) or \(n(A)\), Let \(A=\{1,2,3,4,5,6\}\) and \(B=\{2,4,6,8\}\), What is the cardinality of \(B ? Mathematicians work to clear up the misunderstandings and false beliefs that people have about mathematics. Shorten all set elements to the given length. It may happen that you're most interested in those with a fixed number of elements, for instance, only the k-element subsets of an n-element set. Click Start Quiz to begin! Even the null set is considered to be the subset of another set. Where necessary, relationships are promoted to entities in their own right: for example, if it is necessary to capture where and when an artist performed a song, a new entity "performance" is introduced (with attributes reflecting the time and place), and the relationship of an artist to a song becomes an indirect relationship via the performance (artist-performs-performance, performance-features-song). If you really want to stress that a function f is a bijection, then P ( S =. Calculator helps you to find find union, intersection, difference and Cartesian product of two a!
