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 solving an expression using PEMDAS?

Back

The first step is to solve any operations inside Parentheses.

Front

How do you handle Exponents in PEMDAS?

Back

You calculate the value of the exponent before moving on to multiplication or division.

Front

In the expression 5 + 2 × 3, which operation do you perform first?

Back

You perform the multiplication first, so 2 × 3 = 6, then add 5 to get 11.

Front

What is the result of the expression 8 - 3 + 2?

Back

The result is 7, as you perform addition and subtraction from left to right.

Front

True or False: In the expression 4 + 6 ÷ 2, you should add 4 and 6 before dividing by 2.

Back

False, you should divide 6 by 2 first, then add 4.

Front

What is the value of 3 × (2 + 4) - 5?

Back

The value is 15. First, calculate (2 + 4) = 6, then 3 × 6 = 18, and finally 18 - 5 = 13.

Front

Which operation is performed first in the expression 10 - 4 ÷ 1 · 5?

Back

Division is performed first.

Front

What is the result of 90 - 5² × 3?

Back

The result is 15. First, calculate 5² = 25, then 25 × 3 = 75, and finally 90 - 75 = 15.

Front

In the expression (18 - 14)² - 6 × 10, what is evaluated first?

Back

(18 - 14) is evaluated first.
