Nope, he did not say that at all. Also 10 - (-15) = 25No , 10 + 15 = 25
Are you saying it doesn't ?
Number line number two. Subtraction. A minus sign simply means go the other way.
So 8 - 3 means that we start at the 8 and then go to the left, instead of to the right 3 spaces. We end up at the 5 so:
8 - 3 = 5
Are you with me so far?
