The Answer is
RIGHT
Rules:1) Write your answer on your board2) When the answer is shown give yourself a
tally for the correct answer3) For an incorrect answer, just do not give
yourself a tally4) This game is meant to be a review to help
you prepare for the quiz and test5) PLEASE do not stress and understand the
slides will move in a quick pace6) GOOD LUCK and HAVE FUN
Let’s start with some ADDITION
STEPS for ADDING1) Look at the signs2) Same signs – ADD
example -5 + -2 = -73) Different signs – SUBTRACT
example -2 + 10 = 8remember you take the sign of the larger integer
3 + -10 =
-7
-33 + -78 =
-111
0.67 + -1.5=
-0.83
-¼ + 6/8 =
½
Everyone’s Fav…. SUBTRACTION
STEPS for SUBTRACTING1) Change subtraction to addition
- 6 – 8 - 6 + -8
or - 5 – (- 9) - 5 + 9
2) Same signs – ADDexample - 6 + -8 = -14
3) Different signs – SUBTRACTexample -5 + 9 = 4 remember you take the sign of the larger integer
-3 – (-11) =
8+
0.3 – 10 =
- 9.7
-5 – 62 =
- 67
14 – 122 =
- 108
Now on to the easier stuff…. MULTIPLICATION
STEPS for MULTIPLYING1) Positive x Positive = Positive 2) Negative x Positive = Negative3) Negative x Negative = Positive
IN OTHER WORDS… Same Sign = Positive Different Signs = Negative
-0.5 × 0.5 =
-0.25
2 (100) =
200
-4 × -1 × -2=
-8
1.5 or 1½
1 ( 2) (3)4
-32 =
9-3 × -3
-33 =
-27-3 × -3 × -3
Exponent Rules with Negative Integers• Even exponents = POSITIVE
• Odd exponents = NEGATIVE
Last but NOT Least…. DIVISION
STEPS for DIVIDING 1) Positive ÷ Positive = Positive 2) Negative ÷ Positive = Negative3) Negative ÷ Negative = Positive
IN OTHER WORDS… Same Sign = Positive Different Signs = Negative
-2 ÷ -5 =
0.4
- ¾ ÷ ½ =
- 1 ½
0 / -2.55 =
0
Bringing it ALL Together…
Now that we know all the operations we can do multi-step algorithms…
Just do not forget…
PEMDAS
(-5) (-8) + 7 – 17=
30
-42 + (-3 – (-12)=
25

-25 + - 100 =
-132
