Solve 317 + 45: Vertical Format Addition Practice

Question

$\begin{aligned} &317 \\ +& \\ &~~45 \\ &\underline{\phantom{776}} & \\ \end{aligned}$

00:05 Let's solve this problem together!

00:08 We'll combine two digits at a time.

00:12 Start by adding the ones digits.

00:15 Write down the sum, and if needed, carry 1 to the tens.

00:19 Now add the tens digits. Don't forget to add that 1.

00:24 Place the result in the tens spot.

00:27 Don't forget to fill any missing digits with 0.

00:31 Next, add the hundreds digits and place the sum in the hundreds spot.

00:35 And that's how we solve this problem!

To solve this problem, we'll carry out vertical addition:

Step 1: Add the rightmost digits (units place): $7 + 5 = 12$ . Since 12 is more than 9, we write 2 in the units place and carry over 1 to the tens place.
Step 2: Add the tens place along with the carried-over digit: $1 + 1 + 4 = 6$ . Write 6 in the tens place.
Step 3: Add the hundreds place: $3 + (0 \text{ since there is no hundreds digit from 45}) = 3$ . Write 3 in the hundreds place.

Therefore, the sum of the numbers 317 and 45 is $\mathbf{362}$ .

The correct choice from the given options that matches this sum is choice 4: $362$ .
