Numerical Expressions

Description

Example 4 shows the multiplication of two negative integers: (-8) × (-3). The solution demonstrates that when multiplying two negative numbers, the result is always positive. In this case, (-8) × (-3) = 24.

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, 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 also help students develop flexibility in their problem-solving approaches.

Teacher's Script: Here's an interesting case: when we multiply two negative numbers, the result is always positive. This might seem counterintuitive at first, but it's a crucial rule to remember. Think about it as the negative signs canceling each other out. As we practice more, this rule will become second nature to you.
