Order of Operations and Exponents

The video tutorial covers lesson 6 on the order of operations, focusing on expressions involving addition, subtraction, multiplication, and division. It explains the importance of performing multiplication and division before addition and subtraction. The tutorial introduces the PEMDAS rule, which stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction, and demonstrates how to apply it to solve complex expressions. Through examples, the video illustrates the correct sequence of operations to ensure accurate results.

Which operations should be performed first when solving an expression with only addition, subtraction, multiplication, and division?

• Addition and subtraction

• Multiplication and division

• Subtraction and division

• Addition and multiplication
