Subtract. –8 – 8?

– 8 – (– 8) = – 8 + 8 = 0

= - 8 - (- 8)
= - 8 + 8
= 0

Answer: 0
Note: If subtract - 8 by the same number you will be left with nothing. In subtracting the subtrahend changes to opposite sign. In this case, - 8 becomes + 8.

Proof (going back):
= 0 + (- 8)
= 0 - 8
= - 8

The answer is zero. Remember the old high school mantra, 2 minuses make a plus?
