you people seem smart - I bet you've use latex before - here's something cool to sign up to: https://www.overleaf.com?r=5ce2f3a4&rm=t&rs=b Its so much better then google docs.

(a+b)(a-b)=b(a-b) -> You cannot divide by (a-b), because a = b, therefore (a - b) = 0.

@thestrangest wow that looks amazing

Haha I ended 3 good chats on accident like that..never came to see them again. I hope you'll find him here.
