I'm only an arts student, but I still did a bit of math in my day. Using the fantastic equipment available to me I can't seem to get around not enjoying this. Hit me if this old news, I just get bored and start doing random.
a = b
a2 = ab
a2 - b2 = ab - b2
(a+b)(a-b) = b(a-b)
a+b = b
a+a = a
2a = a
2 = 1
And with that, everything makes sense now!
Main point asking, how does this make sense? I know in arts 'beer = dinner' but in the realm of math, can such atrocities exist?
