Front

What does PEMDAS stand for?

Back

PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

What is the first step in the order of operations?

Back

The first step in the order of operations is to solve expressions inside Parentheses.

Front

How do you handle multiplication and division in the order of operations?

Back

Multiplication and division are handled from left to right, whichever comes first.

Front

How do you handle addition and subtraction in the order of operations?

Back

Addition and subtraction are also handled from left to right, whichever comes first.

Front

What is the result of 8 + 2 x 5?

Back

The result is 18, because you perform the multiplication first (2 x 5 = 10), then add 8.

Front

True or False: In the expression 3 + 4 x 2, you should add 3 and 4 first.

Back

False. You should multiply 4 and 2 first, then add 3.

Front

What is the value of 6 + (2 x 3) - 4?

Back

The value is 8. First, calculate (2 x 3) = 6, then 6 + 6 - 4 = 8.

Front

What is the result of 12 ÷ 4 + 3 x 2?

Back

The result is 9. First, divide 12 by 4 to get 3, then multiply 3 by 2 to get 6, and finally add 3 + 6.

Front

What is the order of operations when evaluating the expression 5 + 2 x (3 + 4)?

Back

First, evaluate the expression in parentheses (3 + 4 = 7), then multiply 2 x 7 = 14, and finally add 5 + 14 = 19.

Front

What is the result of 5 x (2 + 3) - 4?

Back

The result is 21. First, calculate (2 + 3) = 5, then 5 x 5 = 25, and finally 25 - 4 = 21.
