Math Example--Numerical Expressions--Multiplying Integers: Example 12

Topic

Numerical Expressions

Description

Example 12 demonstrates the multiplication of three negative integers: -6, -2, and -8. The solution shows that when multiplying three negative numbers, the result is negative. In this case, (-6) × (-2) × (-8) = -96.

This collection of examples covers various scenarios of integer multiplication, helping students understand the rules governing the multiplication of positive and negative numbers. By presenting different combinations of negative integers, students can recognize patterns and develop a solid foundation for more complex mathematical operations.

Providing multiple worked-out examples is essential for students to fully grasp mathematical concepts. As they encounter various problems solved using consistent principles, students can build a deeper understanding and become more adept at solving problems independently. The slight variations in examples, such as using all negative factors, help students develop flexibility in their problem-solving approaches.

Teacher's Script: Now we have an example with all negative factors. Remember our rule: when we have an odd number of negative factors, the product is negative. In this case, we have three negative numbers, which is an odd number, so our result is negative. This example helps reinforce the importance of counting the number of negative factors to determine the sign of the product.
