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.

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

a = 2

b = 18

What is c ? round your answer to one significant digit (i.e., if the result is 6.741 write 6.7 as your answer).
