Q:
Do I need to be good at math to become a hacker?
A:
No. Hacking uses very little formal mathematics or arithmetic. In particular, you won't usually need trigonometry, calculus or analysis (there are exceptions to this in a handful of specific application areas like 3-D computer graphics).
ESR confirmed for retard, yet again.
