get them to have the same demoninator. like if you have 5/6-3/4 make it 10/12-9/12. then just subtract.
because its just one of the rules of math :)

If the number has a + sign then you add it, if it has a - sign, then you subtract it.
You would have to convert the units to be alike, then you would be able to add and subtract them.
