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

### Instruction:
 Bill anajaribu kuhesabu watoto wachanga katika kituo chake cha kulea watoto, lakini wanakimbia huku na kule. Anahesabu watoto wachanga mara mbili na anapoteza 3 ambao wanajificha. Ikiwa Bill anaamini amehesabu watoto wachanga 26, kuna watoto wangapi kwa kweli?


### Response:
 Kwanza, toa watoto wachanga 8 ambao Bill alihesabu mara mbili kutoka kwenye hesabu yake: watoto wachanga 26 - watoto wachanga 8 = <<26-8=18>>18 watoto wachanga
Kisha, ongeza watoto wachanga 3 ambao alikosa ili kupata hesabu halisi: watoto wachanga 18 + watoto wachanga 3 = <<18+3=21>>21 watoto wachanga
