Overview
Think of the coordinate system as a kind of unit, like meters or inches.

Any measurement is put in terms of the coordinate system in which the measurement was taken. The math is straightforward when dealing with quantities in the same coordinate system, just as adding 2 meters + 3 meters is trivial addition. It is only when changing the coordinate system that a conversion must take place. Mixing values from different coordinate systems results in nonsensical values. On the other hand, working with different coordinate systems depending on the context can also make life easier - just as using miles to measure the distance used by a car might be more useful than using millimeters.
