Question

what is the additive inverse of a/3

Answer 1

-(a/3)

Answer 2

The 'additive inverse' is the thing you can add that will make it equal 0.


0 being the additive identity.

Answer 3

1 is the multiplicative identity! :)

Answer 4

\[{a \over 3} - {a \over 3} = 0 \qquad\quad\;\cdots(1) \]\[\\ {a \over 3} + \left(-{a \over 3}\right) = 0 \quad\cdots(2) \]And since we add -a/3 to make 0, we have -a/3 as the additive inverse.
