  • Hello, I am Billy and i will tell you about the Order of Operations.

Transcript

  • 1. Order of Operations By: Billy Heming
  • 2. What Are the Order of Operations
    • Parentheses (and Division Bars)
    • Exponents
    • Multiplication
    • Division
    • Addition
    • Subraction
    •  
    • You can remember these with the acronym PEMDAS
    •  
    • P LEASE E XCUSE M Y D EAR A UNT S ALLY
  • 3. Starting a Problem
    • ALWAYS START A PROBLEM BY WRITING PEMDAS NEXT TO THE PROBLEM
  • 4. P arentheses       (        )
      • Parentheses and Division Bars are first in PEMDAS.
      • Do what is inside them first when starting a problem
      • When you get inside the parentheses, start over with PEMDAS
      • Example:
          • 5(4+6x7)=
          • 5(4+42)=
          • 5(46)=
          • 230
    •  
    •  
      • When you have a division bar, do what is on the top and then divide the top number by the bottom number.
      • Example:
          •   6+18 =24 =3
    •                      8       8
  • 5. E xponents     52
      • Exponents are the same as powers.
      • Solve exponents after all parentheses and division bars are solved.
      • Example:
          • 24x2=32
        • 24is equal to 2x2x2x2
            •              4x2x2
            •              8x2
            •              16
  • 6. M ultiplication and  D ivision     10x3    20/5
      • You start multiplication and division after all parentheses, division bars, and exponents are solved.
      • When solving multiplication and division, you go from left to right.
      • Say you have 20 divided by 2 times 3, for example, you would not do 2 times 3 and then divide 20 by 6.
      • Instead you would divide because it is first from left to right. 20 divided by 2 equals 10. Then you multiply 10 and 3, which equals 30. That is your answer.
  • 7. A ddition and S ubtraction     8+7     20-13
      • Addition and subtraction are started after everything else is finished.
      • Just like multiplication and division, you go from left to right.
      • Examples:
          • 8+7=15
          • 20-13=7
        • Another example with both:
            • 27+43-50=
            • First, you do 27+43=70
            • Now subtract. 70-50=20
  • 8. Checking your work
      • Checking your work is very important.
      • Make sure to always check your work.
      • You can check with a calculator or by hand.
