Math Example--Numerical Expressions--Multiplying Integers: Example 8

Topic

Numerical Expressions

Description

Example 8 depicts the multiplication of three integers with a negative number at the beginning: (-6) × 3 × 5. The solution shows that the position of the negative number doesn't affect the result, which is negative when there's an odd number of negative factors. In this case, (-6) × 3 × 5 = -90.

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 in various positions, 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 position of negative numbers, help students develop flexibility in their problem-solving approaches.

Teacher's Script: In this example, we see the negative number at the beginning of our multiplication. Remember, just like in our previous example, the position of the negative number doesn't change our result. We still have an odd number of negative factors, so our product is negative. This consistency in rules helps us predict outcomes in more complex calculations.
