What is the first step in solving an expression using PEMDAS?

Back

The first step is to solve any operations inside Parentheses.

Front

Back

You perform whichever comes first in the expression as you read it from left to right.

Front

Evaluate the expression: 3 + 5 × 2

Back

13 (First, multiply 5 × 2 = 10, then add 3).

Front

Evaluate the expression: (6 + 2) × 3

Back

24 (First, add 6 + 2 = 8, then multiply by 3).

Front

What is an exponent?

Back

An exponent is a number that shows how many times to multiply the base by itself.

Front

Evaluate the expression: 2² + 3 × 4

Back

14 (First, calculate 2² = 4, then 3 × 4 = 12, and finally add 4 + 12).
