Let A1, A2, T be non-empty sets such that A1 is bijective to A2.
Show that A1 × T is bijective to A2 × T
So far I've been able to show that for any b where b is an element of A2, there must be some a within A1 such that f(a) = b. I've been able to do the same for proving injectivity between A1 and A2. I just can't figure out how to apply this to A1 x T and A2 x T.
