Order of Operations Review

Front

What is the Order of Operations?

Back

A set of rules that determines the sequence in which calculations are performed in a mathematical expression.

Front

What does PEMDAS stand for?

Back

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

Front

What operation do you perform first in the expression: 5 + 2 × 3?

Back

Multiplication (2 × 3 = 6), then Addition (5 + 6 = 11).

Front

What does it mean to evaluate an expression?

Back

To calculate the value of the expression by performing the operations according to the order of operations.

Front

In the expression (4 + 3) × 2, what should you do first?

Back

Calculate the value inside the parentheses: 4 + 3 = 7.

Front

What is the result of 3 + 4 × 2?

Back

11 (because you do the multiplication first: 4 × 2 = 8, then add 3).

Front

What is the value of 2 × (3 + 5) - 4?

Back

12 (first calculate inside the parentheses: 3 + 5 = 8, then 2 × 8 = 16, and finally 16 - 4 = 12).

Front

What does 3² mean?

Back

3 × 3 = 9.

Front

In the expression 10 - 2 + 4, which operation do you perform first?

Back

You perform the subtraction and addition from left to right, so 10 - 2 = 8, then 8 + 4 = 12.

Front

What is the result of 8 + 3(5 + 2) - 7 × 2?

Back

15 (first calculate inside the parentheses: 5 + 2 = 7, then 3 × 7 = 21, then 8 + 21 - 14 = 15).
