What is -15 minus 0?

Explanation:
Subtracting zero doesn’t change a number. When you have -15 and subtract 0, you’re removing nothing, so the value stays the same. This follows the rule a − 0 = a, so -15 − 0 = -15. The result isn’t 0, 15, or -30 because none of those would come from subtracting zero.
