In mathematics, the concept of an additive inverse is a crucial one. Essentially, an additive inverse of any given number is the number that, when added to the original number, will result in zero. Take for instance the number 5. Its additive inverse is -5, because when you add 5 and -5, the sum is zero. The method to find the additive inverse of a number is straightforward: simply switch the sign. If the number is positive, make it negative and vice-versa.
