Re:What is the inverse of a circle? by joshuaissac on Monday January 31, 2022 @05:48AM (#30146653)
The multiplicative inverse of a number n can be seen as the inverse of the function that multiplies its input by n. That is, the inverse of multiplication by n is multiplication by 1/n.

Similarly, the additive inverse of a number m is the inverse of the function that adds m to its input.
