No. A negative minus a positive is just increasing the negative.
It is definitely C.
-16 -(-4) is the same as -16 + 4, which is -12.
yes... she is right
so negative and negative is a positive, positive and positive is positive
what about positive and negative and negative and positive
i get mixed up on those
16 - 4 = 12 -16 + 4 = -12
-16 + 4 = decreaseing the negative
If you think about the number line it makes a lot more sense.
