High school math was hell for me.<p>The teacher would explain something on the board. Everyone but me would say &#x27;Ohhh, I see&#x27; or similar (think Bart Simpson and the &#x27;RDRR&#x27; gag).<p>The teacher would explain the concept to me again. I still wouldn&#x27;t get it. I got a &#x27;Really?&#x27; look from the teacher, who then walked off.<p>So I wasn&#x27;t a &#x27;math person&#x27;.<p>Then halfway through a thesis I encountered some math that I had to understand and use, or give up the thesis.<p>I discovered I could some math after all.
