Order of Operations Practice

This video tutorial introduces the order of operations, a set of rules for evaluating mathematical expressions. It explains the four main steps: parentheses, exponents, multiplication and division, and addition and subtraction. The video critiques the common acronym 'Please Excuse My Dear Aunt Sallie' for implying six steps instead of four. Several examples are provided to illustrate the application of these rules, emphasizing the importance of following the correct order to achieve accurate results.

What is the first step in the order of operations?

• Add and subtract

• Calculate within parentheses

• Multiply and divide

Which of the following is true about multiplication and division in the order of operations?

• They have the same priority and are done from left to right

• They are not part of the order of operations

• Division always comes before multiplication

• Multiplication always comes before division

What does the acronym 'Please Excuse My Dear Aunt Sallie' incorrectly suggest?

• There are six steps in the order of operations
