Topic

Numerical Expressions

Description

Example 3 demonstrates the multiplication of a negative integer by a positive integer: (-7) × 6. The solution shows that when multiplying a negative number by a positive number, the result is always negative. In this case, (-7) × 6 = -42.

This collection of examples explores 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.

Exposure to multiple worked-out examples is crucial 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 proficient at solving problems independently. The slight variations in examples also help students develop flexibility in their problem-solving approaches.

Teacher's Script: In this example, we're multiplying a negative number by a positive number. Notice that the order doesn't matter - whether we multiply a positive by a negative or a negative by a positive, the result is always negative. This consistency in rules helps us predict outcomes in more complex calculations.
