Simplifying an expression order of operation pemdas

The video tutorial explains how to solve mathematical problems using the order of operations, specifically following the PEMDAS rule (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). It emphasizes the importance of handling nested parentheses first, then moving on to exponents, and ensuring multiplication and division are completed before addition and subtraction. The tutorial provides a step-by-step approach to avoid common mistakes and ensure accuracy in calculations.

What is the first step in the order of operations according to PEMDAS?

• Subtraction

• Addition

• Parentheses

• Multiplication

When simplifying expressions, what should you do after handling the innermost parentheses?

• Proceed to subtraction

• Ignore the rest

• Move to exponents

• Start with addition

How do you handle a double negative in an expression?

• Treat it as a subtraction

• Convert it to a positive

• Ignore it

• Multiply it by two

What operation should be performed first: multiplication or addition?

• It doesn't matter

• Addition

• Subtraction

• Multiplication

In the expression '-7 times -3', what is the result?

• -21

• 0

• 21

• -10
