Calculate the Sum: 228 + 512 in Vertical Format

To solve this problem, we'll perform the vertical addition of the given numbers:

• Step 1: Write the numbers $228$ and $512$ vertically aligned by place value:

$\begin{array}{c} \\ &228 \\ + &512 \\ \hline \end{array}$

• Step 2: Add the digits in the ones column ($8 + 2$). This sum is $10$. Write down $0$ in the ones place and carry over $1$ to the tens column.

$\begin{array}{c} 1 \\ &228 \\ +&512 \\ \hline & ?0 \\ \end{array}$

• Step 3: Add the digits in the tens column ($2 + 1$) along with the carry of $1$. This gives $4$. Write $4$ in the tens place.

$\begin{array}{c} &228 \\ +&512 \\ \hline & ?40 \\ \end{array}$

• Step 4: Add the digits in the hundreds column ($2 + 5$). This sum is $7$. Write down $7$ in the hundreds place.

$\begin{array}{c} &228 \\ +&512 \\ \hline &740 \\ \end{array}$

Thus, the final answer is $740$.

Therefore, the solution to the problem is $740$.
