Phil and Andre decide to order some pizza. They get a small cheese and a large pepperoni. The small pizza has 8 slices, The large has 14 slices. They have both eaten 9 slices already. How many pieces are left per person?
There are 22 pieces of pizza because 14 plus 8 equals <T>add(14, 8)=22
They have eaten 18 pieces of pizza because 9 plus 9 equals <T>add(9, 9)=18
There are 4 pieces of pizza left because 22 minus 18 equals <T>subtract(22, 18)=4
There are 2 pieces per person because 4 divided by 2 equals <T>divide(4, 2)=2.0
