  1. P.E.M.D.A.S By: Samuel Corso
  2. What is P.E.M.D.A.S? P.E.M.D.A.S is the acronym we use to explain the order of ooperations. The order of operations are Parentheses, Exponents, Multiply, Divide, Add or Subtract. We must use this order to solve problems with multiple sign being used.
  3. Parentheses You may see Parentheses like ( or ) to show that this is part of the problem that must be computed first. Parentheses may go around multiple numbers and signs. Example: (9+67)x36 76x36=2736
  4. Exponents Exponents are basically the fancy name for powers on numbers. They mean that there is a number raised to a base number. To show an exponent you may use a sign like ^ before the power. Example: 7^2x4 49x4=196
  5. Multiply The next stetp to P.E.M.D.A.S is to multiply, then divide to make the equasion easier, but you may also multiply or divide left to right. Multiplication is done normally in order of operations. Example: 9x5-3 40-3=37
  6. Divide After multipling, its time to divide. Dividing is also done regularlly in order of operations. We should divide left to right, but it is not necessary. Example: 6/3-1 2-1=1
  7. Add Now it is tiime to add. We can add or subtract left to right, but is usually easier to add first. We add normally. Example: 7+4-3 11-3=8
  8. Subtract The last step before computing your answer is to subtract. As I said, we do not need to subtract for multiplying going left to right, but you may. Subtract normally, then its time to compute your answer. Example: 7-5+4 2+4=6
  9. Check One important thing to do once you have computed your answer is to check it. First, check your math with a calculator, then make sure that you have answered the question entirely. Example: First Answer Once Checked 3x4/6-1 3x4/6-1 12/6-1 12/6-1 6-1=5 2-1=1
  10. My Question What is (5+21)x(6/2)-4 ? Remember to check!
