But, I'm gonna need someone to actually explain it to me...

anonymous · Answer

But thanks for your help anyway :P

welshfella · Answer

On that site i quoted it says that the property is 
-(a+b)=(-a)+(-b)

wher a and b are 2 numbers

so we could fit say 5 amd 7 for a and b  giving

-(5 + 7) = (-5) + (-7)
-12 = -12

welshfella · Answer

- it look like D  to me
what do you think?

welshfella · Answer

in D  a = -6 and b = 17

anonymous · Answer

So that property is when an equation does something like this? (3+5) - (3) + (5)
