Question: Range derived from inequalities

Novice question

I have two sets of inequalties:

s1:= (0<x, x<100)

s2:= (5<x, x<95)

I want each set to define a "range", so I can do set operations on the ranges. For example I want to determine that S2 is a subset of S1, S1 - S2 would give me (0<x, x<=5, 95<=x, x<100), S1 Union S2 = (0<x, x<100), etc


I assume these are simple things that can be done with Maple - but I am not sure how! Any suggestions?
