Order of Operations and Simplification

The video tutorial explains how to evaluate and simplify mathematical expressions using the order of operations. It covers the four steps involved: simplifying within parentheses, performing multiplication and division from left to right, and finally, adding and subtracting from left to right. The tutorial provides a detailed example, demonstrating each step to simplify an expression to its final value.

What is the first step in the order of operations?

• Simplify within the innermost parentheses

• Add and subtract from left to right

• Evaluate exponents

• Multiply and divide from left to right
