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

### Instruction:
On his calculator, August had solved a math problem with an answer of 600. The following math problem had an answer twice as big as the answer of the first math problem, and the third math problem had an answer 400 less than the combined total answers of the first and the second math problems. What's the total of August's answers from solving the three math problems on his calculator?

### Response:
 Ikiwa jibu la tatizo la kwanza la hesabu lilikuwa 600, jibu la tatizo la pili la hesabu lilikuwa mara mbili ya 600, ambayo ni 600*2=1200
Tatizo la tatu la hesabu lilikuwa na jibu 400 chini ya jumla ya majibu ya tatizo la kwanza na la pili la hesabu, jumla ya 1200+600=1800.
Jibu la tatizo la tatu la hesabu lilikuwa 1800-400=1400
Jumla ya majibu ya matatizo matatu ya hesabu ya August kwenye kikokotoo chake ni 1400+1200+600=3200
