Nicole's Multiplying Integers Scribepost

I agree with Justin for the first part because if you multiply a positive integer by a negative integer it would me a negative integer.
But for the second part I don't agree because it would be positive if you remove 5 by a negative number.





a) (+2) x (+4) = +8
b) (+3) x (-5) = -15

(If the integer signs are the same the product is positive, if the integer signs are different/opposite the product is negative)

a) (+10) x (+4) = +40

b) (+6) x (-5) = -30

c) (-7) x (+5) = -35

d) (-8) x (-4) = +32
