About the Book
Subdition is diff erent from any tool used in the educational system today. Subdition is a revolutionary way of determining the difference between two numbers. In Subdition there is no need to regroup or borrow. Within Subdition these terms are obsolete. Instead, Subdition asks the student to identify one of three conditions that exist withina subtraction problem. We refer to these conditions as the Subdition Rules, which you and your child will learn.
