    Undergrad Disproving A = B if A × C = B × C with a counterexample

    Thanks. I tried keeping set C as an empty set. It worked. Cheers :)

    Undergrad Disproving A = B if A × C = B × C with a counterexample

    Hi , Can anyone please give me an idea to disprove the following with counter example: A , B & C be sets. If A X C = B X C , the A = B . I tried giving random numbers in venn diagram but didn't work. And, using subset way to prove equal but still couldn't solve it.
