Question

What is the additive inverse of 0

Answer 1

In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite (number), sign change, and negation. For a real number, it reverses its sign: the opposite to a positive number is negative, and the opposite to a negative number is positive.

Zero is the additive inverse of itself. The number 0 is the only number with its additive inverse being itself.
