If there is a distributive property of multiplication over subtraction (which there is) then a(b-c) = ab-ac for all real numbers, and ad-ac=a(d-c) for all real numbers. It sounds like they just want you to show this with specific examples like

2(4-3)=2(1)=2 solved without distribution
2(4-3)=2*4-2*3=8-6=2 same answer with distribution

Just come up with some more examples like that.

You gotta be kidding me. The whole idea of this assignment is to prove to yourself that the distributive property works without having to do a formal proof. If you won't do this for yourself, you might as well drop the course.

from what i hear, your problem's solution is that subtracting is just adding a negative so it works.
