Solve 317 + 45: Vertical Format Addition Practice

Question

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

00:00 Solve

00:03 Each time consider combining 2 digits, and then write down

00:06 Let's start by adding ones with ones

00:09 Write down the ones, and carry 1 to the tens

00:13 Add tens with tens, remember to add 1 to the calculation

00:19 Write down in the tens place

00:22 Write 0 in the missing digits

00:25 Add hundreds with hundreds, write in the hundreds place

00:28 And this is the solution to the 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: $362$ .
