This document provides information and examples about integer operations: - Addition of integers follows the same rules as normal addition, such as 20 + 10 = 30 and -40 + -60 = -100. - Subtraction of integers is performed similarly to addition, such as -3 - 7 = -10 and 15 - 9 = 6. - When multiplying integers, the product is positive if the signs are the same and negative if the signs are different, exemplified as -2 × 6 = -12 and 2 × -3 = -6. - For division of integers, the quotient is positive if the signs are the same and negative if the signs are different, with examples like 12 ÷ -4 =
