Mrs. Beydoun

2. Objectives: Day 1 Monday October 30, 2017
I can use order of operation to evaluate expressions.
SLOT:
-72 ÷ 9 = _____ = _____ -2
55 ÷ (-5) = _____ = _____ 2

3. Notes (power point)
Practice

4. Evaluating Algebraic Expression
*To evaluate an algebraic expression is to find the value of the expression.
STEPS:
1. Substitute the given value for the variables
(replace letters with the given numbers)
2. Solve using the order of operations (PEMDAS)

5. Example : Solution : 2x + 5y = 2 (4) + 5 (2) = 8 + 10 = 18
Evaluate 2x + 5y when x = 4 and
y = 2
Solution :
2x + 5y
= 2 (4) + 5 (2) =
= 18

6. Evaluate p+2q+ 3r given p = 2 q = 4, r = 6
=2+ 2(4) + 3(6) =
=28

7. Example : Evaluate 3c + 5 if c = 5 and d = 1 4d Solution := 4
= 20
= 5

8. I can use order of operation to evaluate expressions.
