If the problem is d + (-d), then the answer is 0. Suppose that d = 7. Then it would be 7 + (-7), which is 0. You can't get any other number from that equation unless you do d + d or d - d.
Hope this helps.

5 times because with common denominaters(remeber:what you do the top you always do to the bottom or what you do the bottom you do to the top)7/8=21/24 1/6=4/24.21 divided by 4 equals 5.5 but you want a whole loaf of cheese bread not a half so you would round it to 5.
