Write an expression and solve:
Janie's account has $72 in it. If she paid $38 for groceries, how much is in her account now?
LABEL YOUR ANSWER!
72 - 38
= $34
81 + (-15)+ (-28) =
-38
Write as addition and solve:
-12 - (-19) - 4
-12 + 19 + (-4)
= 3

DOUBLE POINTS!
Solving using Order of Operations:
(18 - 26) + 4(-7)
Parenthesis --> (-8) + 4(-7)
Multiply --> (-8) + (-28)
Add --> -36
937 + (-203) + 61

Write as addition and solve:
-7 - 10 - (-5)
-7 + (-10) + 5
= -12

Write an expression and solve:
Marcus went cliff jumping at Saguaro Lake. He fell 24 feet in 4 seconds. What integer represents he far he fell per second?
LABEL YOUR ANSWER
Expression: -24 / 4
Answer: -6 feet per second
-284 + 733 + (-529) + (-319)
-399
Write as addition and solve:
-72 - 84 - (-99)
-72 + (-84) + 99
= -57
If you multiplied 7 negative numbers and 4 positive numbers together, what would the sign of your answer be and why?
You must explain why to get points!
Negative
Multiplying any number of positives will be a positive result. Multiplying an odd number of negatives will be a negative result.
1260 / (-4) / (-15) / (-7)
-3
Solving using Order of Operations:
14 / (-2) - 8(-11) / 4
Divide --> -7 - 8(-11) / 4
Multiply --> -7 - (-88) / 4
Divide --> -7 - (-22)
Rewrite --> -7 + 22
