how do I have to change the resistance if I want to run more than one led?

Do I just add up the led values and plug into the equation? For instance: one Led Is 3.4fv and runs at .100 amps so 14.4-3.4/.100=110 ohms and two
leds is 6.8fv and .200 so 14.4-6.8/.200=38 ohms.

Is that how it works?
 












Thanks tahts darn usefull.
