Lesson to be used by EDI-trained teachers only. Concept Development Positive integers can be shown with a (+) sign or with no sign at all. Negative integers must be shown with a (-) sign. The multiplication and division integer rules are determined by the signs of the integers used. An integer is a positive whole number or negative whole number. Multiplication and Division Integer Rules +3 and 3 Positive Integer -3 Negative Integer Same Sign The product or quotient will be positive. Different Sign The product or quotient will be negative.
