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

### Instruction:
 Ian alikuwa na maua ishirini. Alimpa mama yake maua sita, bibi yake maua tisa, dada yake maua manne, na aliyobaki aliweka. Ian alibaki na maua mangapi?


### Response:
 Idadi ya jumla ya maua ambayo Ian alimpa mama yake na bibi yake ni sita + tisa = <<6+9=15>>15.
Idadi ya jumla ya maua ambayo alimpa mama yake, bibi yake, na dada yake ni 15 + manne = <<15+4=19>>19.
Kwa hiyo, Ian alibaki na maua moja kati ya ishirini - 19 = <<20-19=1>>1.
