Given:
A number is 400.
To find:
The additive inverse of 400.
Solution:
We know that the sum of a number and its additive inverse is 0.
If "a" is number and "b" is its additive inverse, then

Let x be the additive inverse of 400. Then,

Subtract both sides by 400.


Therefore, the additive inverse of 400 is
.
