Numerical Expressions

Description

Example 1 demonstrates the multiplication of two positive integers: 3 × 5. The solution shows that when multiplying two positive numbers, the result is always positive. In this case, 3 × 5 = 15.

Numerical expressions are fundamental in mathematics, representing values through various operations like addition, subtraction, multiplication, and division. This collection of examples illustrates different scenarios of integer multiplication, helping students recognize patterns and develop strategies for solving numerical problems effectively.

Exposure to multiple worked-out examples is crucial for students to fully grasp mathematical concepts. By seeing various problems solved using the same principles, students can build a deeper understanding and become better equipped to solve problems independently. Additionally, slight variations in examples can reveal different approaches to similar problems, fostering critical thinking and adaptability in problem-solving.

Teacher's Script: Class, let's start with a simple example of multiplying two positive integers. Notice how the product of two positive numbers is always positive. This is an important rule to remember as we move on to more complex examples involving negative numbers.
