Publisher's Synopsis
Integers are numbers such as -5, 0, and 232. This book contains 12,000 questions on addition and subtraction, with a cameo appearance by multiplication. The first half of the book offers quizzes to work on, while the second half reprints each question and offers the solution. Many of the questions are paired to allow the reader to understand equivalent expressions such as -16-(-11) and -16+11. A short introduction reviews rules of addition and subtraction.
