This book had SO many typos and statements that didn’t make sense. Here are a few a copied and pasted:

Saying the mental math equivalent of multiplying by 5 was to multiply by 10, then divide by 5 (should be multiply by 10 and divide by 2)

Using words like “diving” and “decide” when he meant divide on page 28

Using the word “sum” for the result of a division result (when it is the result of an addition).

But in addition to these (and more) errors/typos, the book was supposed to cover mental math strategies and he is saying to ask a friend, or Google the answer to your math question, or read a book, or listen to an audio book if you can’t read (!!) or to consult an “academician”. This book was just really really bad.

This book was not what I was expecting and I find the title somewhat misleading. I was expecting a book that taught patterns and complex tricks that could be used to add big numbers rapidly.
Instead this book turned out to be the kind of thing you would pass to someone who had always used a calculator for the simplest of problems (like 12+7)
Some of the seventy tips included things like "If you want to add without a calculator take advantage of search engines." or "use mathematical tables from bookstores" or "Count on your fingers, this will lead to a faster solution" the last tip in the book was "Ask a friend."
