Multiplying Rules
Positive x Positive = Positive
4 x 5 = 20
Negative x Negative = Positive
(-2) x (-6) = 12
Negative x Positive = Negative
(-3) x (9) = (-27)
Positive x Negative = Negative
6 x (-3) = (-18)
Dividing Rules
Positive / Positive = Positive
15 / 3 = 5
Negative / Negative = Positive
(-20) / (-4) = 5
Negative / Positive = Negative
(-6) / 3 = (-2)
Positive / Negative = Negative
8 / (-4) = (-2)
Adding Rules
Positive + Positive = Positive
4 + 7 = 11
Negative + Negative = Negative
(-5) + (-3) = (-8)
(Basically add the numbers and put back the negative sign)
Sum of a negative and positive number: Subtract the smaller number from the larger number and put back the sign of the larger number.
(-6) + 4
To get the answer: Subtract 4 from 6 : 6 - 4 =2
6 has a negative sign, therefore the answer is (-2)
(-6) + 4 = (-2)
Subtracting Rules
Negative - Positive = Negative
(-5) - 4 = (-9)
Positive - Negative = Positive + Positive = Positive
5 - (-6) = 5 + 6 = 11
Negative - Negative = Negative + Positive : Subtract the smaller number from the larger number and use the sign of the larger number.
(-7) - (-2) = (-7) + 2 = -5
Positive x Positive = Positive
4 x 5 = 20
Negative x Negative = Positive
(-2) x (-6) = 12
Negative x Positive = Negative
(-3) x (9) = (-27)
Positive x Negative = Negative
6 x (-3) = (-18)
