Question

What is additive inverse? ​

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, 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

Answer:

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, 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.

Loosely speaking, an additive inverse of a field element a is an element b such that a+b=b+a=0. It turns out that only one additive inverse exists for each element. For example, over the rational numbers, the additive inverse of 25 is −25 and the additive inverse of −5 is 5.
