## Order of Operations

Warm up:

-3 +5 x6 mult

-3 + 30 battle pos win =27

### Warm Up 30

• -3 - 3 / 2 divide

• -3 - 1.5 isolate minus ssf

• -3 + -1.5 add negatives 3.0

• -4.5 1.5

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

### 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

### Practice underlining steps and writing what we do #4

(4 squared÷ 8) – 5 exponent ( )

( 16 ÷ 8 ) – 5division in ( )

2 – 5isolate minus ssf

2 + -5battle neg’s win
