  1. Order of Operations Warm up: -3 +5 x6 mult -3 + 30 battle pos win =27

  2. Warm Up 30 • -3 - 3 / 2 divide • -3 - 1.5 isolate minus ssf • -3 + -1.5 add negatives 3.0 • -4.5 1.5

  3. Grouping Symbols (), [ ], { } or fraction bar Exponents Division or Multiplication, whichever comes first from left to right Subtraction or addition, whichever comes first from left to right Example: #12 (8sq.÷ 5cubed) ÷ 5 + 3 8 x 8 = 64 5x5x5 = 25 x5 = 125 (64 ÷ 125) ÷ 5 + 3 .512 ÷ 5 + 3 0.1024 + 3 3.1024 Toolbox HW: evens on ws (2-12) show all steps and write rule for each Order of Operations Steps and Example

  4. Problem #2 Homework Example • 3 + (9 - 3squared + 1 – 1) exponent • 3 + (9 - 9 +1 -1) do subtraction • 3 + ( 0 +1 -1 ) do addition • 3 + (1 – 1) do subtraction • 3 + 0 = 3

  5. Practice underlining steps and writing what we do #4 (4 squared÷ 8) – 5 exponent ( ) ( 16 ÷ 8 ) – 5 division in ( ) 2 – 5 isolate minus ssf 2 + -5 battle neg’s win -3

  6. Exit Quesion • (5 + 7) x 1 – 8 Good Luck
