Order of Operations and Basic Arithmetic

This video tutorial explains the order of operations in mathematics, which is crucial for evaluating expressions correctly. It covers the four main steps: simplifying within parentheses, handling exponents, performing multiplication and division from left to right, and finally, addition and subtraction from left to right. The tutorial provides examples to illustrate each step, ensuring a clear understanding of how to simplify complex expressions accurately.

What is the first step in the order of operations?

• Simplify all expressions with exponents
