Order of Operations

  1. 1. Order of Operations <br />By: Cincia Dervishaj <br />Grade 7<br />
  2. 2. Order Of Operations Procedure<br /><ul><li>To do the Order of Operations you have to follow “PEMDAS” .
  3. 3. “PEMDAS” stands for:
  4. 4. Parentheses
  5. 5. Exponents
  6. 6. Multiplication and Division
  7. 7. Addition and Subtraction</li></li></ul><li>Parentheses<br /><ul><li>Parentheses is the first operation you do.
  8. 8. Another word for Parentheses is “Bracket”
  9. 9. Parentheses look like this: (). An example of an equation with parentheses would be:
  10. 10. (4+8)-7=3 The Parentheses are in blue. </li></li></ul><li>Exponents <br /><ul><li>The next operation is exponents.
  11. 11. Exponents look like this: ab
  12. 12. When doing exponents you multiply the number on the bottom by the amount of times of the raised number. Ex:
  13. 13. 42= 4x4=16</li></li></ul><li>Multiplication and Division<br /><ul><li>Following Exponents is multiplication and division. When doing multiplication and division you do the symbol that comes first from left to right.
  14. 14. An example would be:
  15. 15. 10x2/4=5 but if you did it the other way you would get a different awnser10/2x4=20 </li></li></ul><li>Addition and Subtraction<br /><ul><li>The last two letters stand for Addition and Subtraction.
  16. 16. Like multiplication and division when doing addition and subtraction you do what comes first from left to right.
  17. 17. An example of this is:
  18. 18. 20+2-4=18 but when doing it reversed 20-2+4=18 it will still equal 18. </li></li></ul><li>Extra Tips <br /><ul><li>Another way to remember “PEMDAS” is:
  19. 19. “Please Excuse My Dear Aunt Sally”
  20. 20. If you remember this and the steps mentioned you will find Order of Operations easy. </li></li></ul><li>Now You Try It<br />Q: You have four numbers and the numbers equal up to 60. You are aloud to use a pair of parentheses two multiplication signs and one division sign. You are not allowed to move the numbers from there position. Where do the signs go?<br /> 4 5 6 2<br />
