Order of Operations and Exponents

This lesson covers the importance of following the order of operations in math to ensure consistent solutions. It explains the hierarchy of operations: parentheses, exponents, multiplication/division, and addition/subtraction. Through examples and practice problems, students learn to apply these rules to solve expressions correctly, emphasizing the global standard of PEMDAS.

Why is it important to follow the order of operations in mathematical expressions?

• To avoid using parentheses

• To use fewer mathematical symbols

• To make calculations faster

• To ensure consistency in results

What is the first step in the order of operations?
