zero.
Anything minus itself is zero.

Zero minus zero equals zero.
Well, darling, three minus zero is still three. It's like asking if a cat is still a cat without whiskers - of course it is! So, in this case, three minus zero is a solid three. Next question, please!

Suppose x and y are two POSITIVE numbers so that -x and -y are negative. Then a negative minus a negative = (-x) - (-y) = -x +y If x > y the answer is negative If x = y the answer is zero If x < y the answer is positive
zero
If you mean subtracting a negative number from another negative, then you simply add the second negative to the first number. For example: -3 - (-4)=1 -3 + 4 = 1 The double negative makes the equation an addition.
