Using the Sets Solver to solve Seys Quick example

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}
Use the keyword "Find" to ask a question. Below are examples of acceptable questions. ( Note that you should use the Union symbol ∪ provided on the calculator button. Do not use the letter u from the keyboard.)
    Find A ∩ B
    Find A ∪ B ∪ C
    Find (A ∪ B) ∩ C
    Find A ∩ (B ∪ C)
    Find (A ∪ B) ∩ (A ∪ C)
    Find A' ∩ B'
    Find n(A ∩ B)
    Find |A ∩ B|
Finally Click the Solve button to find the full solution.
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)'
