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

### Instruction:
 Cristina, John, Clarissa na Sarah wanataka kumpa mama yao albamu ya picha kama zawadi ya siku yake ya kuzaliwa. Cristina analeta picha 7, John analeta picha 10 na Sarah analeta picha 9. Ikiwa albamu ya picha ina nafasi 40, Clarissa anahitaji kuja na picha ngapi ili kukamilisha albamu ya picha?


### Response:
 Bila kuhesabu Clarissa, kuna picha 7 + 10 + 9 = <<7+10+9=26>>26.
Clarissa anahitaji kuja na picha 40 - 26 = <<40-26=14>>14 ili kukamilisha albamu ya picha.
