This document provides a review of integer operations including addition, subtraction, multiplication, and division. It gives the rules for determining the sign of the answer when combining integers with the same or different signs. Examples are worked out step-by-step of adding, subtracting, multiplying, and dividing integers. The document is to be completed as an assignment by a student for practice with integer operations.
