The additive inverse is just a number with the opposite sign. For example, 7 is -7. For example, 8 is -8. For example, -2 is 2. Really easy!!!!!!!!!!!!!!!
The additive inverse of a number N is the element which when added to N produces the unity element for addition (zero). So... N and -N are additive inverses of each other. To get the additive inverse of a number, multiply the number by -1. More specific examples of additive inverses: (-5, 5), (3, -3), (1.4, -1.4)
The additive inverse is just the same number with the opposite sign. Additive inverse of 6 is -6. Additive inverse of -3 is 3.
The additive inverse of a number is the number that, when added to the original number, gives zero. It's fairly obvious that the additive inverse of any number is just that number with the opposite sign in front of it, e.g. the additive inverse of 7 is -7, because 7 + (-7) = 0
