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
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
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
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
Bringing it ALL Together…
Now that we know all the operations we can do multi-step algorithms…
Just do not forget…
