Add 765 and 549.

• A. 1313
• B. 1314
• C. 1315
• D. 1310

Answer: (B)

Adding multi-digit numbers by lining up the digits in columns and handling carries when a column sums to 10 or more is the idea here. Start with the units: 5 plus 9 equals 14, so write down 4 and carry 1 to the tens. In the tens column, 6 plus 4 plus the carried 1 equals 11, so write down 1 and carry 1 again. In the hundreds column, 7 plus 5 plus the carried 1 equals 13, so write down 3 and carry 1 to a new thousands place. That extra carry becomes the thousands digit, so you place 1 there. Put it all together and the sum is 1,314.

This outcome reflects the carries from each column correctly propagating through the addition. The other options would require different carry patterns or final digits that don’t match these column sums.
