The second math problem had an answer twice as big as the answer of the first math problem, so 600 x 2 = 1200
The combined total answers of the first and second math problems is 600 + 1200 = 1800
The third math problem had an answer 400 less than the combined total answers of the first and second math problems, so 1800 - 400 = 1400
The total of August's answers from solving the three math problems is 600 + 1200 + 1400 = 3200
#### 3200
The answer is: 3200
