Question 778283
<pre>
The additive inverse of {{{-5/2}}} is {{{5/2}}} because that's
what you have to add to {{{-5/2}}} to get the additive identity 0.

{{{-5/2}}} + {{{5/2}}} = 0

Asking 

"What is the additive inverse of this number?" 

is the same as asking 

"What number must I add to this number to get 0 as an answer?"
