Jose is a collector of fine wines.  His private cellar currently holds 2400 bottles of imported wine and half as many bottles of domestic wine as imported wine.  If Jose holds a party and the guests drink one-third of all his wine, how many bottles will remain in his cellar?
Jose has half as many bottles of domestic wine as imported wine, or 2400/2=<T>divide(2400, 2)=1200.0 bottles of domestic wine.
In total, he has 2400+1200=<T>add(2400, 1200)=3600 bottles of wine.
If the guests drink one-third of all his wine, then they will have consumed 3600/3=<T>divide(3600, 3)=1200.0 bottles of wine.
Thus, after the party, Jose's private cellar will have 3600-1200=<T>subtract(3600, 1200)=2400 remaining bottles of wine.
