Math Example--Numerical Expressions--Multiplying Integers: Example 10

Topic

Numerical Expressions

Description

Example 10 illustrates the multiplication of three integers: -5, 4, and -6. The solution demonstrates that when multiplying three integers with two negative numbers and one positive number, the result is positive. In this case, (-5) × 4 × (-6) = 120.

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 positive and 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 changing the order and values of factors, help students develop flexibility in their problem-solving approaches.

Teacher's Script: Let's look at another example with two negative numbers and one positive number. Notice how the order of the factors doesn't affect our result - we still get a positive product because we have an even number of negative factors. This reinforces the importance of focusing on the number of negative factors rather than their position or specific values.
