Order Of Operations[1]

  1. 1. Order of Operations<br />By: Brianna McBratney<br />7th Grade<br />
  2. 2. PEMDAS<br />Steps to order of operations<br />A way to remember these steps is : Please Excuse My Dear Aunt Sally<br />P = parentheses <br />E = exponents<br />M = multiplication<br />D = division<br />A = addition<br />S = subtraction<br />
  3. 3. Parentheses<br />If you see parentheses you start with that by adding, subtracting, dividing, or multiplying.<br />Example<br />2(3x4)-2<br />3x4=12<br />2x12=24<br />24-2=22<br />Answer: 22<br />
  4. 4. Exponents <br />When you have a number like 2 with an exponent of 4 this means you times 2 by its self 4 times.<br />Example: 2x2x2x2=8<br />2(6x5)+2 exponent 4<br />6x5= 30<br />30+8= 38<br />38x2=76<br />Answer: 76<br />
  5. 5. Multiplication & Division<br />You multiply first and then divide after you do parentheses and exponents .<br />Example<br />5x5-6/1<br />5x5=25<br />6/1= 6<br />25-6= 19<br />Answer: 19<br />
  6. 6. Adding & Subtracting<br />Add or Subtract regularly after all the steps of parentheses, exponents, and multiplying and dividing.<br />Example Example:<br />3(4x2)-5 3(4x2)+5<br />4x2= 8 4X2= 8<br />8x3= 24 8X3= 24<br />24-5= 19 24+5= 29<br />Answer: 19 Answer: 29<br />
  7. 7. Solve<br />3(15x5)-3/2+ 6<br />
