Amaze and mystify your friends! Benjamin has performed his "art of rapid mental calculation" for audiences of all ages and levels of mathematical sophistication, and now he reveals his secrets to you. Actually, most of these calculation and memorization techniques are fairly commonly known, but Benjamin explains how to perform them to great effect. He uses simple algebraic proofs to show how the tricks work and often adds an anecdote about how he "discovered" an interesting trick. This is a book to ignite mathematical confidence and curiosity. A word of warning, though: despite the subtitle, it will take some dedicated practice to master these tricks. For most collections.

My college students are amazed when I can square a 2-digit number quicker than they can punch it in on a calculator. (I'm not too fast at the 3 digit numbers; it's hard to teach an old dog new tricks!)
I highly recommend this book for math teachers, school libraries, students, or anyone at all!
