To find the distance between Neptune and Mars, we need to subtract the distance from Earth to Mars from the distance from Earth to Neptune.

4.3514x10^9 km - 2.25x10^8 km = 4.3514x10^9 km - 0.225x10^9 km

Subtracting gives us:

= 4.1264x10^9 km

Therefore, Neptune is 4.1264x10^9 km farther from Earth than Mars.
