To add the given numbers, we add the ones place first, which gives us 5. We write down 5 in the answer and "carry over" 1 to the tens place. Then we add the tens place, which gives us 2 + 8 + 1 (the "carried over" 1) = 11. We write down 1 in the answer and "carry over" 1 to the hundreds place. Finally, we add the hundreds place, which gives us 1 + 7 = 8. Therefore, the answer is 923. To add these two numbers, we simply add the digits in the ones place (5+8), which equals 13. We then carry the 1 over to the tens place and add those digits (8+3+1), which equals 12. Finally, we add the digit in the hundreds place (1). Putting it all together, we get 923. However, since the original problem had a positive and a negative number, we need to indicate the sign of our answer based on the larger absolute value. In this case, 738 has a larger absolute value than 185, so the answer is positive. Therefore, the correct choice is C) 553.
