Difficult concepts in areas such as statistics, probability, trigonometry and calculus are explained in an easy to understand format using cartoons and drawings. This makes self-learning easy for both the child and any teacher whose math skills are a little rusty.

One of Beestar teacher liked to use this book. It turned out to be one of the best books I've bought for my son. Great math methods are taught throughout the book. It provides many questions of different levels after each method, which suits all types of kids in different learning stages. My son understands Beestar questions better after this reading this book. He moved fast to the top ranking among Beestar peers. This book will last until middle school, so it's a good investment!
