can you brake -4_-9 down to me

I think you mean -4 - (-9) This reads as (-4) subtract (-9)

Now when we subtract a negative number, it is the same as adding a positive number

So this becomes (-4) + 9

                         = 5

(start at -4 on the number line  and move 9 places to the right, you get 5)
