#+2sqrt16 - 2sqrt16 =0#

These terms are known as additive inverses.

They have exactly the same value, but one is positive and one is negative.
One is a 'give', the other is a 'take'.

The sum of additive inverses is always #0#.
This works no matter what the values are.
While we could simplify each term, this is not necessary.

#+2sqrt16 - 2sqrt16 =0#
