Step-by-Step Solution

To solve the problem of adding 917 and 5, follow these step-by-step instructions:

Step 1: Line up the numbers vertically by their place values. The hundreds place, tens place, and units place should be aligned:

$\begin{aligned} &917 \\ +& \\ &~~~5 \\ &\underline{\phantom{776}} \\ \end{aligned}$

Step 2: Begin with the units place (rightmost column). Add $7$ and $5$ . The sum is $12$ .

Since $12$ is greater than $9$ , we write down $2$ and carry over $1$ to the tens place.

Step 3: Proceed to the tens place. Add the digits $1$ (the carried over value) and $1$ (from 917). This gives us $2$ .

We write $2$ in the tens place.

Step 4: Finally, add the hundreds place. Add $9$ (from 917). As there is no shipment here due to the tens column sum, write the $9$ directly.

After completing all the places, the final result is:

$\begin{aligned} &917 \\ +& \\ &~~~5 \\ &\underline{922} \\ \end{aligned}$

Therefore, the answer to the problem is $\boxed{922}$ .
