Front

What does PEMDAS stand for?

Back

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

Front

Calculate: 5 + 2 x 3

Back

11 (Multiplication is performed before addition).

Front

Calculate: (8 - 3) + 2

Back

7 (Subtraction inside parentheses is performed first).

Front

What operation is performed first in the expression: 4 + (6 - 2) x 3?

Back

Subtraction inside the parentheses (6 - 2).

Front

Calculate: 10 - 2 + 3 x 4

Back

20 (Multiplication is performed before addition and subtraction).

Front

Identify the error: 6 + 2 x 5 = 40

Back

The error is in the order of operations; multiplication should be done before addition.

Front

What is the result of: 12 ÷ 4 + 3 x 2?

Back

9 (Division and multiplication are performed before addition).

Front

Calculate: 15 - (3 + 2) x 2

Back

5 (Parentheses are calculated first, then multiplication, then subtraction).

Front

What is the second operation performed in the expression: (10 - 2) + 5 x 2?

Back

Addition (after subtraction inside the parentheses).
