1. ## Geometry question

Hello,

I'd like to start by saying I'm not that good in math, in fact, I know math as much as I know nuclear physics. So please be gentle.

I'm trying to register at a forum and their verification system (to know whether you're a human or a bot) is pretty challenging.

To register, you need to solve this simple math problem.
a = 2
b = 18
I really appreciate the help and sorry if this is in the wrong section.

Do you know the proposition of Phytagoras? Never heard of $a^2+b^2=c^2$?
