This math workbook from the Dr. Pi Squared Math Workbooks series focuses on multi-digit subtraction. There is ample workspace for students to write large answers and still fit their solutions comfortably into the space provided. The problems appear in a large font size, since students usually write larger than standard textbook fonts. High-quality, durable, bright paper is used (instead of standard workbook paper, which often tears easily and appears dull in color). Each section begins with a large, fully-solved example to illustrate the technique and to serve as a useful guide. Answers are nicely organized by page number in the back of the book to allow students, parents, or teachers to quickly check the answers. An aesthetic, full-color addition table is conveniently located on the back cover for easy reference. CONTENTS: (1) Two Digits Minus One Digit, (2) Two Digits Minus Two Digits, (3) Three Digits Minus Three Digits, (4) Four Digits Minus Four Digits, (5) Five Digits Minus Five Digits, (6) Six Digits Minus Six Digits, (7) Seven Digits Minus Seven Digits.
