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

### Instruction:
 Roy ana kalamu za bluu 2. Ana kalamu za nyeusi mara mbili na kalamu za nyekundu mara mbili chini ya kalamu za nyeusi. Roy ana kalamu ngapi jumla?


### Response:
 Roy ana kalamu za nyeusi 2 x 2 = <<2*2=4>>4.
Mara mbili ya idadi ya kalamu za nyeusi ni 4 x 2 = <<4*2=8>>8.
Hivyo, kuna kalamu za nyekundu 8 - 2 = <<8-2=6>>6.
Hivyo, ana kalamu 2 + 6 + 4 = <<2+6+4=12>>12 jumla.
