What relationship do set A and set B have?
A relation from a set A to a set B is a subset of A×B. Hence, a relation R consists of ordered pairs (a,b), where a∈A and b∈B. If (a,b)∈R, we say that is related to , and we also write aRb….Definition: Relation.

Are A and B equivalent sets?
Definition 2: Two sets A and B are said to be equivalent if they have the same cardinality i.e. n(A) = n(B). In general, we can say, two sets are equivalent to each other if the number of elements in both the sets is equal. And it is not necessary that they have same elements, or they are a subset of each other.
Is set null?
In mathematical sets, the null set, also called the empty set, is the set that does not contain anything. It is symbolized or { }. In axiomatic mathematics, zero is defined as the cardinality of (that is, the number of elements in) the null set.
What type of sets are set A and set B if they have at least one common element?
Two sets that have at least one common element are called overlapping sets.
Does Abba give reason?
Answer: The given mathematical statement in the question is partially true. Explanation: The equation will only fulfill when the numerical values of a and b are exactly same.
When is a×B not equal to B×a?
For two unique and non-empty sets A and B, A×B is not equal to B×A. For two sets A and B, the Cartesian product of two sets A×B and B×A are equal if either of the following condition is satisfied: If A = {1, 2} and B = ϕ. Then,
What is the meaning of $a-b=b-a$?
($A-B=B-A$) means that the set of everything in $A$ which is not in $B$ equals the set of everything in $B$ which is not in $A$.
What does a×B stand for?
Cartesian Product For two sets A and B, the Cartesian product of A and B is denoted by A × B and defined as: A×B = { (a,b) | aϵA and bϵB } Cartesian Product is the multiplication of two sets to form the set of all ordered pairs.
What is a B in discrete mathematics for CS?
A B CS 441 Discrete mathematics for CS M. Hauskrecht Set operations Definition: Let A and B be sets. The intersection of A and B, denoted by A B, is the set that contains those elements that are in both A and B. • Alternate: A B = { x | x A x B }. Example: • A = {1,2,3,6} B = { 2, 4, 6, 9} • A B = { 2, 6 } U A B
