Solve Two-Digit Addition: 47 + 22 in Vertical Format

$\begin{aligned} &47 \\ +& \\ &22 \\ &\underline{\phantom{776}} & \\ \end{aligned}$

To solve this problem, we'll follow these steps:

• Step 1: Add the units digits.
• Step 2: Add the tens digits, including any carry-over from the units column.

Let's work through these steps:

Step 1: Add the units digits, which are 7 and 2.

$7 + 2 = 9$.

Since 9 is less than 10, we don't need to carry over to the tens column.

Step 2: Add the tens digits, which are 4 and 2.

$4 + 2 = 6$.

Combine these results: The sum of 47 and 22 is 69.

Therefore, the solution to the problem is $69$.
