To solve the problem of adding 917 and 5, follow these step-by-step instructions:
Since is greater than , we write down and carry over to the tens place.
We write in the tens place.
After completing all the places, the final result is:
Therefore, the answer to the problem is .
922
\( \begin{aligned} &90 \\ +& \\ &~~9\\ &\underline{\phantom{776}} & \\ \end{aligned} \)
We start from the units place (rightmost) because that's where carrying begins! If you start from the left, you won't know if you need to add any carried digits.
When two digits add up to 10 or more, you write the units digit in that column and carry the tens digit to the next column left. It's like exchanging 10 ones for 1 ten!
No! You only carry when the sum in any column is 10 or greater. If 7 + 2 = 9, there's no carrying needed since 9 < 10.
Think of it as adding zero! In 917 + 5, the tens place is really 1 + 0 (plus any carry), and hundreds is 9 + 0.
Try adding horizontally using mental math: 917 + 5. You can also add the numbers in a different order to double-check your result!
