Tips:
When working with rules for positive and negative numbers, try and think of weight loss, or poker games, or baying items to help solidify 'what this works'.
Using a number line showing both sides of 0 is very helpful to help develop the understanding of working with positive and negative numbers/integers.
with positive and negative numbers (integers) you can do: adding, subtracting, multiplying and dividing
Adding Rules:
Positive + Positive = Positive
5 + 4 = 9
Negative + Negative = Negative
(- 7) + (- 2) = - 9
Sum of a negative and a positive number: Use the sign of the larger number and subtract
(- 7) + 4 = -3
Subtracting Rules:
Negative - Positive = Negative
(- 5) - 3 = -5 + (-3) = -8
Positive - Negative = Positive + Positive = Positive
5 - (-3) = 5 + 3 = 8
Negative - Negative = Negative + Positive = Use the sign of the larger number and subtract (Change double negatives to a positive)
(-5) - (-3) = ( -5) + 3 = -2
(-3) - ( -5) = (-3) + 5 = 2
Multiplying Rules:
Positive x Positive = Positive
3 x 2 = 6
Negative x Negative = Positive
(-2) x (-8) = 16
Negative x Positive = Negative
(-3) x 4 = -12
Positive x Negative = Negative
3 x (-4) = -12
Dividing Rules:
Positive � Positive = Positive
12 � 3 = 4
Negative � Negative = Positive
(-12) � (-3) = 4
Negative � Positive = Negative
(-12) � 3 = -4
Positive � Negative = Negative
12 � (-3) = -4
