Barry has $10.00 worth of dimes.  His little brother, Dan has half that amount but finds 2 more dimes on his way home from school.  How many dimes does Dan have?
Dimes are worth $0.10 and Barry has $10.00 worth of dimes so he has 10/.10 = <T>divide(10, 0.1)=100.0 dimes
Dan has half the amount of dimes as Barry so Dan has 100/2 = <T>divide(100, 2)=50.0 dimes
Dan finds 2 more dimes on his way home so he now has 50+2 = <T>add(50, 2)=52 dimes
