See Ya Later Calculator: Simple Math Tricks You Can Do in Your Head

by Portable Press, Bathroom Readers' Institute

A lot of us hate math, but that's just because we don't remember much of it from high school or we think it's too hard (which is probably why we've forgotten it). But who needs it, when you've got a calculator, right? Wrong. We all use math everyday—to calculate a tip, to figure out an interest rate, to estimate the cost of the groceries in your cart, etc. Math doesn't have to be hard. It can be easy, fast, and even fun…if you know how to do it all in your head.

See Ya Later Calculator demystifies numbers and math. With these simple, precise, and downright magical math tricks, readers can do everyday math faster than it takes to dig out their phone and find the calculator app. Clear, step-by-step, easily memorizable directions demonstrate more than 125 math operations anyone can do in their head, such as:

How to easily square any number
How to add three-digit numbers
How to multiply two-digit numbers
How to subtract large numbers

And lots more…no calculator (or pencil and paper) required.

I am so impressed with this I am writing a review. Where was this when I was in high school?

I haven't been in a math class in 13 years and was concerned I wouldn't remember enough to follow along. I was happily surprised with this book. It covered everything I remembered and so much more.

It starts with 5 topics of math then builds on them. The main topics are: General math, Fractions, Algebra, Geometry and Problem Solving. All information is presented via simplified text and examples. There is no more than 3 pages covering a topic/equation and the page layout/format is pleasing to the eye.

I know this book's intention is to aid mental math but this is the textbook you need for the school issued math textbook. This is a fabulous resource. I plan to buy a copy for our library and share it with my colleagues from the Math Department.

3 things I will highlight to Math Connoisseurs:
- It covers compound interest
- It covers Vedic Math.
- There is a formula for figuring out the day of the week you were born. I am somehow crazy excited for this.

Derivative of Previous Works

The Kindle version I purchased was terrible.
The text was okay but the equations and samples were tiny.
Worse the chapter titles were excessively large.
It's just a collection of math tips with little in the way of examples.
Add to it is the very corny attempts at humour.
Scott the Human Calculator did a much better job teaching and applying the skills for daily use.
It wasn't an easy read and I'm being kind giving it Two Stars.

A lot of these “ tricks” I have been using for years, but this would be a good book to use as a reference book for home schooling, or for tutoring math.
