Jim spends 8 hours scuba diving.  In that time he finds a treasure chest with 100 gold coins in it.  He also finds 2 smaller bags that have half as much gold each.  How much gold does he find per hour?
The smaller bags each have 100/2=<T>divide(100, 2)=50.0 gold coins each
So in total, they have 50*2=<T>multiply(50, 2)=100 coins
So he found 100+100=<T>add(100, 100)=200 coins
So he finds 200/8=<T>divide(200, 8)=25.0 coins an hour
