# Math Order of Operations

The following is a quick tutorial on calculating math problems using order of operations based on the acronym PEMDAS, and remember it by saying Please Excuse My Dear Aunt Sally... if you can remember this, you will remember how to solve any math problem that requires order of operations. PEMDAS means:

P - Parenthesis: If there is a parenthesis in the equation, do this first, if not onto the next step.

E - Exponents: If there is an exponent in the equation, do this next, if not, move to the next.

M - Multiplication: If there are numbers that need to be multiplied, do this next... and so on.

D - Divide

A - Add

S - Subtract

For example: if you have an equation that looks like the following, you will solve it according to the acronym (remember PEMDAS):

2(5 + 7)^{2}

Step 1. P (parenthesis)

Because a parenthesis is present in your equation, you will solve what is inside the parenthesis first

5 + 7 is in the parenthesis - 5 + 7 = 12, your formula now looks like this:

2(12)^{2}

Step 2. E (exponents)

Exponents are solved next in order of operations (if they are present in the equation).

12 is to the 2^{nd} power, also known as squared, so you will complete this operation next,

12^{2} = 144

Your equation now looks like this

2(144)

Step 3. M (multiplication)

2 * 144 = 288

There is nothing left to solve so:

2(5 + 7)^{2} = 288.
