I found this book very helpful.

It might be strange that I'm rating a math book with five stars, but this book definitely achieves its goal of introducing concepts without inducing fear in the reader. Contrary to what schoolchildren everywhere insist, there are some math skills that can serve us well on a daily basis - if we can do them quickly and accurately. All the Math You'll Ever Need is a gentle introduction to these particular skills as well as a primer on the general math concepts you'll need.

Included in the book are clear, concise tutorials on skills like calculating tips when out to eat, estimating travel time, finding the area of a wall you'd like to paint, adding fractions when cooking with measuring cups, and calculating interest; readers can navigate to the section for the skill they'd like to improve and read a la carte. For readers who need to practice mental math, or are too far from their elementary-level schooling to recall important properties of numbers, the book features great explanations on multiplication, long division, ratios and percentages, and working with negative numbers. I highly recommend this text for number-crunchers and novices alike.

Kind of a fun book to read -- still feel math-retarded. I have a Master's degree and the only math I ever took was 2 years of high school algebra, which left my mind the instant the class was over. But -- I'm good with a calculator!!

What fun! Easily explained everyday math problems including compound interest, the rule of 70 and those dreaded two trains start together but travel in opposite directions and after 4 hours how far apart are they if one was traveling 20 mph faster.

Great book! All of the calculations are written out so the logic behind them is clear. The writing itself is playful and makes the work seem not too serious. This book is definitely for math for everyday life, and the only unfortunate oversight is that there is no chapter on probability. Otherwise, this book is an excellent reference guide, and it doesn't weigh much.

A good review of basic math. Now I'm ready for Sixth Grade Common Core Math, which was the reason I opened this book in the first place. I didn't want to panic when my grandson asked me for help with his homework.

A little bit too easy. Not that suitable for software engineer.
