Sec 1.1 – Order of Operations pg. 29 - 31

Order of Operations Order of Operations allows us to each evaluate an expression or equation and come up with the SAME answer. P – Parentheses (P)lease E – Exponents (E)xcuse M – Multiplication & (M)y D – Division (D)ear from left to right A – Addition & (A)unt S – Subtraction (S)ally

PEMDAS I generally refer to “order of operations” as PEMDAS problems Evaluate or simplify 5 2 – (2 3 – 6) + 45 ÷ 5 5 2 – (8 – 6) + 45 ÷ 5 5 2 – 2 + 45 ÷ 5 25 – 2 + 45 ÷ 5 25 – 2 + 9 23 + 9 32

Now you try [39 – 3(4 – 2) 2] ÷ 3 [6 – (7+9)] 2 – 11 2 [39 – 3(2) 2] ÷ 3 [39 – 3 (4)] ÷ 3 [39 – 12] ÷ 3 27 ÷ 3 9 [6 – (7+9)] 2 – 11 2 [ 6 – 16] 2 – 11 2 [ -10] 2 – 11 2 100 – 121 -21
