You're doing arithmetic here.  All the units are the same, so you don't have to convert, just add and subtract as necessary.  Are you having trouble setting up the problems so you can solve them?

anonymous · Answer

1) 420 - 98 = 322
2) 480 - (-230) = 480 + 230 = 710
3) 1083 - 659 = 424
4) 212 - (-44) = 212 + 44 = 256

As petiteJiji ands stellarpiper stated. These are simple arithmetic problems which do not involve any conversions.
