Question

What are the multiplicative inverse and additive inverse in math?

Answer 1

The opposite of a number is its additive inverse. A number and its opposite add to 0, which is the additive identity. ... The reciprocal of a number is its multiplicative inverse. A number and its reciprocal multiply to 1, which is the multiplicative identity

Answer 2

The Multiplicative Inverse of a number 'a' is the number that 'a' needs to be multiplied by to give the Muliplicative Identity, 1. It is dentoed by
`(1)/(a)` or
`a^(-1)`. For example the Multiplicative Inverse of 3 is
`(1)/(3)` or
`3^(-1)` because
`3*(1)/(3)=1`.

The Additive Inverse of a number 'a' is the number that needs to be added to 'a' to give the Additive Identity, 0. It is dentoed by
`-a`. For example the Additive Inverse of 3 is
`-3` because
`3+(-3)=0`.
