Mastering the Art of Multiplying and Dividing Integers
Multiplying and dividing integers can be a daunting task for many students. However, with the right strategies and practice, it can become a breeze. In this article, we will explore the rules and techniques for multiplying and dividing integers, and provide you with a comprehensive worksheet to help you master these essential math skills.
Understanding the Rules of Multiplying Integers
When multiplying integers, there are three basic rules to follow:
- Rule 1: When multiplying two positive integers, the result is always positive. For example: 2 × 3 = 6
- Rule 2: When multiplying a positive integer and a negative integer, the result is always negative. For example: 2 × -3 = -6
- Rule 3: When multiplying two negative integers, the result is always positive. For example: -2 × -3 = 6
📝 Note: Remember, when multiplying integers, the sign of the result depends on the signs of the two factors being multiplied.
Understanding the Rules of Dividing Integers
When dividing integers, there are also three basic rules to follow:
- Rule 1: When dividing a positive integer by another positive integer, the result is always positive. For example: 6 ÷ 2 = 3
- Rule 2: When dividing a positive integer by a negative integer, the result is always negative. For example: 6 ÷ -2 = -3
- Rule 3: When dividing a negative integer by another negative integer, the result is always positive. For example: -6 ÷ -2 = 3
📝 Note: Remember, when dividing integers, the sign of the result depends on the signs of the dividend and the divisor.
