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

### Instruction:
An elevator is on the 9th floor. It goes down 7 floors, then up 3  floors, then up 8 floors. If the elevator is on the top floor, how many floors are there in the building?

### Response:
 Kutoka ghorofa ya 9, lift ilishuka hadi ghorofa ya 9 - 7 = <<9-7=2>>2.
Kisha ilipanda hadi ghorofa ya 2 + 3 = <<2+3=5>>5.
Kisha, ilipanda hadi ghorofa ya 5 + 8 = <<5+8=13>>13; hivyo kuna jumla ya ghorofa 13 katika jengo hilo.
