1Order of Operations PEMDAS byAlex GarciaandCameron Rogers
2Order of OperationsThe Order of Operations is the order of solving a mathematical problem.You must solve problems using the 6 operations, working from left to right.
3PEMDAS P – Parentheses E – Exponents M/D – Multiplication or Division Use the acronym PEMDAS to help you remember the Order of OperationsP – ParenthesesE – ExponentsM/D – Multiplication or DivisionA/S – Add or Subtract
4PEMDAS = Parentheses ( ) Parentheses are the 1st operation to look for in a problem. If there are parentheses then you must do the math in them before anything else.Ex: 11 – (2 + 4)2 + 4 = 611 – 6 = 5Before you can do anything else, you must do the operation inside the parentheses.
5PEMDAS = ExponentsThe 2nd operation to look for in a problem are exponents. If there are exponents solve them next.Ex:52 = 25= 32After solving any problems in parentheses, solve all exponents.
6PEMDAS = Multiplication + Division Multiplication and Division are the 3rd operations to look for in a problem. Solve multiplication and division problems working from left to right.Ex: 5 x5 x 6 = 30= 42Ex: 36 ÷ 6 – 436 ÷ 6 = 66 – 4 = 2The 1st operation to do in this equation is multiplication.The 1st operation to do in this equation is division
7PEMDAS = Addition + Subtraction The last two operations to look for in a problem are Addition and Subtraction. Solve these after completing all of the math in Parentheses, Exponents, Multiplication, and Division.Ex: – 65 + 4 = 99 – 6 = 3Ex: 10 – 7 + 410 – 7 = 33 + 4 = 7In this problem you do the Adding first because you have to go from left to right.In this problem though, you do the subtraction first because you solve from left to right.
