Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
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?

### Response:
 Kuna vipande 22 vya pizza kwa sababu 14 plus 8 ni sawa na <<14+8=22>>22.
Wameshakula vipande 18 vya pizza kwa sababu 9 plus 9 ni sawa na <<9+9=18>>18.
Kuna vipande 4 vya pizza vilivyosalia kwa sababu 22 minus 18 ni sawa na <<22-18=4>>4.
Kuna vipande 2 kwa kila mtu kwa sababu 4 kugawanywa na 2 ni sawa na <<4/2=2>>2.
