Order of Operations and Simplification

The video tutorial explains how to simplify mathematical expressions using the order of operations. It emphasizes that multiplication and division, as well as addition and subtraction, have the same priority and should be performed from left to right. Two examples are provided: one involving multiplication and division, and another involving addition and subtraction. The tutorial concludes by verifying the results using a graphing calculator.

When simplifying expressions with multiplication and division, what is the correct order of operations?

• Divide first, then multiply

• Multiply first, then divide

• Multiply and divide from left to right
