Solution Steps

00:04 Let's solve this problem together.

00:07 Each time, we'll calculate the sum of two digits and substitute it.

00:12 Let's begin by adding the ones with the ones.

00:16 Place the sum in the ones position and add one to the tens.

00:21 Now, add the tens with the tens. Don't forget to include that one.

00:26 Put the sum in the tens place and add one to the hundreds.

00:30 Finally, add the hundreds with the hundreds. Include that extra one again.

00:36 And that's how we solve this problem!

Step-by-Step Solution

To solve this problem, we will use the vertical addition method:

Step 1: Align both numbers by their rightmost digits. This means: $683$ on top, $127$ on the bottom.
Step 2: Start adding from the rightmost column (the units place): $3 + 7 = 10$ . Write down $0$ and carry over $1$ to the tens column.
Step 3: Next, move to the tens place: $8 + 2 = 10$ ; add the carried over $1$ : $10 + 1 = 11$ . Write down $1$ and carry over $1$ to the hundreds column.
Step 4: Finally, move to the hundreds place: $6 + 1 = 7$ ; add the carried over $1$ : $7 + 1 = 8$ . Write down $8$ .

The sum of $683$ and $127$ is $810$ .

Therefore, the correct answer is $810$ .
