zepdrix · Answer

A `multiplicative inverse` when multiplied by its inverse gets you to the `multiplicative identity`.

For addition, this identity is 0.
But for multiplication, this identity is 1.

So it's the value you multiply by to get back to 1. :)

So the multiplicative inverse of 2 is 1/2, because 2 * 1/2 = 1

a has a multiplicative inverse 1/a
such that a*1/a=1
1 is called multiplication identity
