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