Front

What is the acronym used to remember the Order of Operations?

Back

PEMDAS (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

Parentheses - solve expressions inside parentheses first.

Front

What do you do after solving parentheses in an expression?

Back

Next, solve any exponents.

Front

In the expression 18 + (6 – 2) × 2, what do you solve first?

Back

The expression inside the parentheses: (6 – 2) = 4.

Front

In the expression 18 − 4 × 2, which operation do you perform first?

Back

Multiplication - 4 × 2 = 8.

Front

What is the result of 18 + (6 – 2) × 2?

Back

26.

Front

In the expression 10 - 4 ÷ 1 x 5, which operation is performed first?

Front

What is the result of 3 + 4 x 6 - 4?

Back

The first step is multiplication: 4 x 6 = 24, then 3 + 24 - 4 = 23.
