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

### Instruction:
 Moto wa kupikia unachoma magogo matatu kila saa. Ilijengwa na magogo sita mwanzoni. Ikiwa inapata magogo mawili zaidi kuongezwa mwishoni mwa kila saa, magogo mangapi yatabaki baada ya masaa matatu?


### Response:
 Baada ya masaa matatu, itakuwa imechoma magogo 3 * 3 = <<3*3=9>>9.
Baada ya masaa matatu, itakuwa imeongeza magogo 6 + 2 * 3 = <<6+2*3=12>>12.
Baada ya masaa matatu, itakuwa imebakiwa na magogo 12 - 9 = <<12-9=3>>3.
