 ## Presentation on theme: "The Answer is RIGHT."— Presentation transcript:

When the answer is shown give yourself a tally for the correct answer For an incorrect answer, just do not give yourself a tally This game is meant to be a review to help you prepare for the quiz and test PLEASE do not stress and understand the slides will move in a quick pace GOOD LUCK and HAVE FUN

STEPS for ADDING 1) Look at the signs 2) Same signs – ADD example  = -7 3) Different signs – SUBTRACT example  = 8 remember you take the sign of the larger integer

= -7

= -111

= -0.83

-¼ + 6/8 =

Everyone’s Fav…. SUBTRACTION
STEPS for SUBTRACTING Change subtraction to addition - 6 – 8 or - 5 – (- 9) 2) Same signs – ADD example  = -14 3) Different signs – SUBTRACT example  = 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 MULTIPLYING Positive x Positive = Positive Negative x Positive = Negative 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

-32 = -3 × -3 9

-33 = -3 × -3 × -3 -27

Exponent Rules with Negative Integers
Even exponents = POSITIVE Odd exponents = NEGATIVE

Last but NOT Least…. DIVISION
STEPS for DIVIDING Positive ÷ Positive = Positive Negative ÷ Positive = Negative Negative ÷ Negative = Positive IN OTHER WORDS… Same Sign = Positive Different Signs = Negative

-2 ÷ -5 = 0.4

- ¾ ÷ ½ = - 1 ½

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

-2(-2) 2×-2= -16

= -132
