Sandra had 2 different bags of candy.  Each of her bags had 6 pieces of candy left.  Her brother, Roger, also had 2 bags of candy.  One of his bags of candy had 11 pieces left and the other had 3 pieces left.  How much more candy did Roger have?
Sandra had 2 bags that each contained 6 pieces of candy so 2*6 = <T>multiply(2, 6)=12 pieces
Roger had 11 pieces of candy in one bag and 3 pieces in the other so 11+3 = <T>add(11, 3)=14 pieces
Roger had 14 pieces and Sandra had 12 pieces so Roger has 14-12 = <T>subtract(14, 12)=2 more pieces of candy
