To add the numbers, start with the ones column: 9+4=13. Write down the 3 and carry over the 1 to the tens column. In the tens column, you have 7+9+1 (from the carry over)=17. Write down the 7 and carry over the 1 to the hundreds column. In the hundreds column, you have 5+4+1 (from the carry over)=10. Write down the 0 and carry over the 1 to the thousands column. Finally, in the thousands column, you have 1+5=6. So the answer is 14,973. To add these two numbers, we start by adding the ones place: 9 + 4 gives us 13. We write down the 3 in the ones place and carry the 1 to the tens place. Now we add the numbers in the tens place: 7 + 9 + 1 (the one we carried over) gives us 17. We write down the 7 in the tens place and carry the 1 to the hundreds place. Finally, we add the numbers in the hundreds place: 5 + 4 + 1 (the one we carried over) gives us 10. We write down the 0 in the hundreds place and carry the 1 to the thousands place. Since we have no more digits to add, we write down the final 1 in the thousands place, giving us the answer of 14,973.
