Additive Inverse of a Number

The additive inverse calculator is a free online tool which can find the additive inverse of any number that is entered. For example, if any number, say, 10 is entered, the tool will find the additive inverse of 10 and give the result as -10.

What is Additive Inverse?

Additive inverse refers to any number that when added to the original number gives the result as zero. For instance, the additive inverse of 8 is -8 as 8 + (-8) = 0. It is possible to get the additive inverse of negative numbers too. For example, the additive inverse of -10 will be 10 as -10 + 10 = 0.
