John plays a game for 4 hours a day every day for 2 weeks.  After all that time, he is only 40% done.  He increased his playtime to 7 hours a day.  How long until he finishes the game?
There are 7*2=<T>multiply(7, 2)=14 days in two weeks
So he played 14*4=<T>multiply(14, 4)=56 hours
That means the total length of the game is 56/.4=<T>divide(56, 0.4)=140.0 hours
So he has 140-56=<T>subtract(140, 56)=84 hours to beat the game
So it will take him 84/7=<T>divide(84, 7)=12.0 days to beat the game
