Another one = two
Assume a = b multiply both sides by a... a squared = ab subtract b squared from both sides... (a squared – b squared) = ab – b squared factorize... (a + b)(a – b) = b(a – b) divide both sides by (a – b)... (a + b) = b Let a = b = 1 2 = 1 QED

Re: Another one = two
a - b = 0. You are dividing by zero.

Re: Another one = two
I liked the calculus one a lot better. This one is very trite. I first heard it when I was about 13, and proudly went to tell my Grandpa that I had a great mathematical paradox. Before I even started it, he said "Oh I expect it's dividing by zero", and I went away disappointed. He didn't say it in a mean way, just as an observation, and he was a Nobel prize winner so I expect quite a lot of things seemed obvious to him! Oh no!! Not again!

Re: Gee, that\'s helpful....
"that we sought is thus demonstrated" Or something to that effect. It means the proof is complete. A guy I knew who took both math and latin I think translated it best: "Whoop there it is"
