Explanation:

Step 1: Calculate 12. \(78 + 195 + 692\)

First, add \(78 + 195 = 273\), then add \(273 + 692 = 965\).

Step 2: Calculate 13. \(675 + 834 + 297\)

First, \(675 + 834 = 1509\), then \(1509 + 297 = 1806\).

Step 3: Calculate 14. \(965 + 1055 + 2430\)

First, \(965 + 1055 = 2020\), then \(2020 + 2430 = 4450\).

Step 4: Calculate 15. \(728 + 692 + 111 + 4376\)

First, \(728 + 692 = 1420\), then \(1420 + 111 = 1531\), then \(1531 + 4376 = 5907\).

Step 5: Calculate 16. \(59 + 77 + 461 + 7954\)

First, \(59 + 77 = 136\), then \(136 + 461 = 597\), then \(597 + 7954 = 8551\).

Step 6: Calculate 17. \(794 + 1429 + 3680 + 5291\)

First, \(794 + 1429 = 2223\), then \(2223 + 3680 = 5903\), then \(5903 + 5291 = 11194\).

Answer:
