Solve Vertical Addition: 352 + 27 Step-by-Step

$\begin{aligned} &352 \\ +& \\ &~~27 \\ &\underline{\phantom{776}} & \\ \end{aligned}$

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

• Step 1: Align the numbers based on place value.
• Step 2: Add each column starting from the right (units column).
• Step 3: Carry over any values greater than 9 to the next column.

Now, let’s work through each step:

Step 1: Align the numbers vertically:

$\begin{array}{c} 352 \\ + 27 \\ \hline \end{array}$

Step 2: Add the right-most column (the units).
$2 + 7 = 9$, write $9$ in the units place.

Step 3: Move to the next column to the left (the tens).
$5 + 2 = 7$, write $7$ in the tens place (no carrying needed).

Step 4: Move to the left-most column (the hundreds).
$3$ remains $3$ as there is nothing to add, so write $3$ in the hundreds place.

Thus, the result when you add the numbers is:

$\begin{array}{c} 352 \\ + 27 \\ \hline 379 \\ \end{array}$

Therefore, the sum of $352$ and $27$ is $379$.
