The story about Gray is one of a young girl who discovers a new way of approaching subtraction. Gone is the old method of crossing out smaller digits above larger digits, which confuses the issue of place value. Instead, students will learn alongside Gray and her friends that there are several ways to do subtraction that allow them to use fundamental mathematical concepts logically. In this book, the authors explain how to take the mystery out of subtraction. This book is a companion for adults to the student book of the same name.
