Solve Three-Digit Addition: 274 + 519 in Vertical Format

To solve this problem, we'll follow these steps for vertical addition:

• Step 1: Add the digits in the units place.
• Step 2: Add the digits in the tens place, remembering to carry over if needed.
• Step 3: Add the digits in the hundreds place, again carrying over if needed.

Let's work through each step:

Step 1: Add the units digits: $4 + 9 = 13$. We write down the 3 and carry over the 1.

Step 2: Add the tens digits, including the carried over 1: $7 + 1 + 1 = 9$. Write down 9.

Step 3: Add the hundreds digits: $2 + 5 = 7$. No need to carry over as the sum is less than 10. Write down 7.

The final sum from our calculation is 793, written directly below the line in the vertical addition setup.

Therefore, the solution to the problem is $793$.
