Getting worse at mental arithmetic

[FuturePhysicist]

Hello I have a question reguarding human calculation. I'm in high school and I have been called a "math whiz" when it comes to subjects like algebra or calculus. But my school has kids using calculators so much that I haven't been using my head much for calculations. Because of this, I feel like an idiot every time I do arithmetic in my head. I was practically a math prodigy when I was little but now I feel like a fool. I was thinking about reading the book "Secrets of Mental Math" by Arthur Benjamin, but i felt like that would be cheating or something.
P.S. I don't even remember multiplication or division on paper!

That's a fun book. Not cheating at all, just some clever methods. (That require practice.)

I put "mental arithmetic" in a completely different category from algebra and calculus. Good clean fun.

Okay, looks like I will be adding that book to my shelf then. Thank you.
