Evaluating Mathematical Expressions

The video tutorial focuses on evaluating numerical expressions using the order of operations, emphasizing the importance of solving expressions within parentheses first. It provides examples such as 8 - 3 + 3, 5 * (11 + 1), (6 + 12) / 3, and 29 - 0 * 9, demonstrating how to simplify each step-by-step.

Why is it important to evaluate expressions inside parentheses first?

• It simplifies the expression.

• It makes the expression longer.

• It is a rule of thumb.

• It is optional.
