5.0 out of 5 stars
I think it's a great book that can help a lot with math.,

This review is from: Cool Math (Paperback)
I like that it tells the history of math and numbers. It tells a lot of cool math tricks that can really help people. It tells a lot about Pi like how to remember the first 8 decimal places. It also tells quick facts about math, like the boy in Japan who took Pi to 40,000 decimal places. It took him 15 hours. I really like the book, and I suggest that other kids read it.

This review is from: Cool Math (Paperback)
The author is clearly struggling with the materialleading to significant mistakes throughout (e.g. whole numbers are confused with rationals, the four color "solution" is muddled, history is garbled-- not to mention B.C.E. and A.D. being juxtaposed on the time line). It's a shame because a diligent editor could have caught these in time for revision.
