Explain how to simplify the expression -98 - 31? Using the additive inverse.

Given:

The expression is -98 - 31.

To find:

The value of the given expression using the additive inverse.

Solution:

According to the  additive inverse, for any number a,

Using additive inverse, we have

     ...(i)

          ...(ii)

Now, using (i) and (ii), we get

Subtracting 129 from both sides, we get

Therefore, the value of given expression is -129.
