Secrets of Mental Math: The Mathemagician's Guide to Lightning Calculation and Amazing Math Tricks

in

I was bored. So I read it. Nice book. But there is a better one for people who knows a bit more than middle school math. I saw some nice puns(Magic "square" indeed... as in magic square that consist of perfect squares only). Def. recommend it for people who want to learn faster mental math. BTW I don't care about how fast one can evaluate basic functions mentally. I read so many books these days, going to post them like one per day. The author Arthur T. Benjamin wrote another book, Proofs that Really Count: The Art of Combinatorial Proof (Dolciani Mathematical Expositions). Which won a award from MAA. Going to check that out soon.
But before that...
