Exploring PEMDAS with Fraction Bars

This video tutorial teaches how to evaluate expressions with fraction bars using the correct order of operations. It explains that a fraction bar acts as a division sign and a grouping symbol, requiring all operations in the numerator and denominator to be completed before division. The video provides three example problems, demonstrating step-by-step solutions while emphasizing the importance of following the order of operations.

What is the first step in evaluating expressions with a fraction bar?

• Add the numerator and the denominator

• Perform all operations in the numerator

• Divide the numerator by the denominator

• Perform all operations in the denominator

What is the purpose of the fraction bar in an expression?

• To subtract the numerator from the denominator

• To multiply the numerator and the denominator

• To divide the numerator by the denominator

• To add the numerator and the denominator
