Mastering the Order of Operations with PEMDAS

The video tutorial explains the order of operations using the PEMDAS rule, which stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. It provides examples of solving mathematical expressions by following this order, emphasizing the importance of working from left to right. The tutorial also covers how to handle mixed operations and offers various examples to illustrate these concepts.

What does the letter 'P' in PEMDAS stand for?

• Product

• Parentheses

• Percentage

• Power

In the expression '67 - 21 + 20', which operation should be performed first according to PEMDAS?

• None, as there is no multiplication or division

• Multiplication

• Subtraction

• Addition

If an expression includes both multiplication and division, in which order should these operations be performed?

• Always perform multiplication first

• In the order they appear from left to right

• Multiplication before division

• Division before multiplication

• 480

• 360

• 7.5

• 6

What is the correct sequence to solve the expression '28 times 5 minus 7' using PEMDAS?

• Multiplication, then subtraction

• Subtraction, then multiplication

• Division, then addition

• Addition, then division

In the expression '100 + 50 divided by 2 - 25', what is the first operation to perform?

• Addition

• Subtraction

• Division

• Multiplication

What is the final result of the expression '25 times 8 minus 3 divided by 2'?

• 198.5
