 * __ The Order Of Operations__**

In algebra, there are some situations where a problem has more than one expression. It isn't always clear where to start. There is a rule that is specifically for these situations. It is called the order of operations.

The Order Of Operations is used when a problem has more then one operation.


 * __Summary__**

The Order of Operations is an easy way to find the answer to a multiple operation problem. Mostly algebra problems are the ones that you have to use the order of operations to solve. Without the Order of Operations, the example problems below would be very hard.

Parentheses Exponents Multiplication Division Addition Subtraction
 * PEMDAS**

Please Excuse My Dear Aunt Sally

Parentheses **outrank** exponents. Exponents **outrank** multiplication and division because multiplication and division are on the //same// rank. Multiplication and division **outrank** addition and subtraction because they are on the bottom rank // together .//

 * __Steps__**

If there are any parentheses in the problem start there. After parentheses comes exponents. Always keep the number you got in your head. Then look for any multiplication signs or division signs. Look for these together because they are on the same rank, therefore they go together.(read above) Then addition and/or subtraction are also on the same rank so do those from left to right. Then you have your answer! (this is the PEMDAS method, read above.)

2+8-3x2=4 5-1+7+9=20 4x2+1-2=7 4/2+13x4=54
 * __Easy Problems__**

5+3-1(3+4)x2=21 6-2+8x9+7=75 1x3+3x2-4=8 10-7+30-15x2=3
 * __Medium Problems__**


 * __Hard Problems__**

5x3-6(7+6)+1=19 7+(6x3)-3+2-9=15 9x6(3x4)2+6=74 5+3^2x(4/4)-2=12
