Hi guys, I saw this on the web. I haven't done any math in a while and I can't seem to find where the error is, but I'm sure there is one. I'm sure I must of forgotten some simple algebra rule but I can't stop thinking about this problem.
a = b
a^2 = ab
a^2 - b^2 = ab – b^2
(a + b)(a – b) = b(a – b)
(a + b) = b
a + a = a
2a = a
2 = 1
a = b
a^2 = ab
a^2 - b^2 = ab – b^2
(a + b)(a – b) = b(a – b)
(a + b) = b
a + a = a
2a = a
2 = 1
