In each of the following cases, find A-B and B-A:
A = {x : x is an integer divisible by 3}, B = {x : x is a positive integer}

Find the union of each of the following pairs of set : A = {x : x is a natural number and multiple of 3} B = {x : x is a natural number less than 6}

Find the intersection of each of the following pairs of set :- A ={x : x is a natural number and multiple of 3} B = {x : x is a natural number less than 6}

Which of the following pairs of sets are disjoint:- {x : x is an even integer } and {x : x is an odd integer}

List all the elements of the following set : B = {x : x is an integer, -1/2 < x < 9/2 }

The set {x:x is an integer and -3 < x le 2 } is equal to:

In the following, state whether A = B or not: A ={2.4, 6, 8, 10} B = { x : x is positive even integer and x le 10 }

Prove that the following pairs of sets are disjoint A={x:x is an even integer], B=[x:x is an odd number]

Write the converse of the following statement : If two integers a and b are such that a > b, then (a-b) is always a positive integer.

Prove that the following relation R in Z of integers is an equivalence relation : R = [ (x, y) : 3x- 3y is an integer}
