Oh, I don't hide it at all. You will see my fingers moving like I'm signaling someone. All I was really doing was simple additions and subtractions. Yes, I need my fingers to do 7+5, and I'm not ashamed of it.
After all, I aced my standardized math tests including SAT, what is now called SAT II math(s), AP calculus (both) and GMAT.
Ya, I aced my SAT's too!
Pics or it didn't happen
