When doing more complex math problems, meaning you are not simply adding, subtracting, multiplying or dividing but are doing a combination of these methods, in order to arrive at the correct answer you must follow a certain order. This order is known as the Order of Operation.
The Order of Operation can easily be remembered by remembering the following letters: PEMDAS. Broken down you get:
P = Parentheses
E = Exponents (Powers and Square Roots)
MD = Multiplication and Division (Left to Right)
AS = Addition and Subtraction (Left to Right)
Now what does this mean? If the problem presented to you has parentheses in it, you always do the math within the parentheses first.
After the math is done inside the parentheses, you then do all the multiplication and divisions operations followed by any addition and subtraction operations.
Let’s look at the following math problem as an example:
(16 + 21) x 4 - 36 ÷ 6 =
We know we must work the numbers inside of the parentheses first so, 16 + 21 = 37.
Next we must do the multiplications and division so, 37 x 4 = 148 and 36 ÷ 6 = 6.
The problem should now look like 148 – 6 and the answer is that it equals 142.
