Math Example--Numerical Expressions--Multiplying Integers: Example 6

Topic

Numerical Expressions

Description

Example 6 demonstrates the multiplication of three integers, including a negative number: 3 × 6 × (-4). The solution shows that when multiplying multiple numbers with one negative factor, the result is negative. In this case, 3 × 6 × (-4) = -72.

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, including multiple factors and negative numbers, 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 introducing multiple factors and negative numbers, help students develop flexibility in their problem-solving approaches.

Teacher's Script: In this example, we're multiplying three numbers, and one of them is negative. Remember our rule: if there's an odd number of negative factors, the product will be negative. Here, we have one negative factor, so our result is negative. Keep this in mind as we work with more complex problems involving multiple factors.
