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…
