What does PEMDAS stand for?

Back

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

Front

Calculate: 3 + 4 x 6 - 4

Back

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

Front

Calculate: (7 + 41) ÷ 2 – 15

Back

First, solve inside the parentheses: 7 + 41 = 48, then 48 ÷ 2 = 24, and finally 24 - 15 = 9.

Front

Calculate: 15 + 7 × 2 – 11 + 35

Back

First, multiplication: 7 x 2 = 14, then 15 + 14 - 11 + 35 = 53.

Front

Calculate: (9 + 23) ÷ (5 - 3)

Back

First, solve inside the parentheses: 9 + 23 = 32 and 5 - 3 = 2, then 32 ÷ 2 = 16.

Front

Calculate: 14 + 8 x 7 - 3

Back

First, multiplication: 8 x 7 = 56, then 14 + 56 - 3 = 67.

Front

What is the first step in solving 5 + 2 x 3?

Back

The first step is multiplication: 2 x 3 = 6.

Front

What is the result of 8 - 3 + 2 x 4?

Back

First, multiplication: 2 x 4 = 8, then 8 - 3 + 8 = 13.

Front

What is the importance of parentheses in order of operations?

Back

Parentheses indicate which operations should be performed first.
