## How to use the Set Solver

##### Begin by typing the question. Each question should begin with a Universal set U. Examples of acceptable inputs of universal set :

U = {x:1 ≤ x ≤ 12 , x is an integer}

U = {x:x is an integer, 1 ≤ x ≤ 12 }

U = {x|1 ≤ x ≤ 12 , x is an integer}

U = {x|x is an integer, 1 ≤ x ≤ 12 }

U = {1,2,3,4,5,6,7,8,9,10,11 }

U = {a,b,c,d,e,f,g}

##### Then add 2 or 3 sub sets. Each set should be represented by a capital letter e.g A,B,C etc. Examples of acceptable inputs for subsets are:

A = {x:x is a prime number}

B = {x:x is a multiple of 4}

C = {x:x is a divisible by 3}

P = {x:x is a factor of 20}

Q = {x:x is a an even number}

R = {x:x is a an odd number}

M = {x:x is a perfect square}

N = {x:x is a perfect cube}

T = {2,4,6,8}

S = {r,i,ce}

##### A standard input will be like as follows:

U = {x:1 ≤ x ≤ 10, x is an integer}

A = {x:x is an odd number}

B = {x:x is an even number}

C = {x:x is a prime number}

Find (A ∩ B)' ∪ (A ∩ C)'
