Understanding Exponents and Order of Operations

The video tutorial explains how to simplify mathematical expressions by focusing on exponents and the order of operations. It highlights the importance of distinguishing between negative exponents and squaring negative numbers. The tutorial also covers how to sum integers with different signs and uses a money analogy to verify the results, ensuring a clear understanding of the concepts.

What is the first step in simplifying an expression without parentheses?

• Add and subtract
