Using a property of operations, what can you say about the sums of (-13.2) 8.1 and 13.2 (-8.1)

artcher [175]

No matter where the negative sign is, the product will always be negative, so is the number itself.

13.2(-8.1)=-106.92

twice of that would be -213.84.

first do the multiplying, then the adding(the adding of negative numbers, so it would be basically subtracting).
