Description:
Using proven techniques, this volume shows how to add, subtract, multiply and divide faster than is possible with a calculator or pencil and paper, and helps readers conquer their nervousness about math.
After seeing Dr. Benjamin perform in Las Vegas at the National Council of Teachers of Mathematics conference in 2002, I bought this book and also his Mathemagics course. My middle school students love it! Many of them prefer to do mental calculations when possible and they love when I do mathematic magic tricks on them.
Better, they love the algebraic explanations and can't wait to use the tricks on their friends and family, knowing that they can explain the trick as well.
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!
