Front

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

Back

The first step is to evaluate any expressions inside Parentheses.

Front

What is the result of 3 + 5 x 2 according to PEMDAS?

Back

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

Front

Evaluate: 4 + (6 - 2) x 3

Back

16 (First evaluate inside the parentheses: 6 - 2 = 4, then multiply: 4 x 3 = 12, and finally add: 4 + 12 = 16.)

Front

What is the value of 2^3?

Back

8 (2 raised to the power of 3 is 2 x 2 x 2 = 8.)
