Solve Addition Problem: 936 + 79 in Vertical Format

To solve this problem, we'll proceed with vertical addition:

• Step 1: Align the numbers.

Align the numbers so that their place values line up:

$\begin{array}{c} & 936 \\ + & 79 \\ \hline \end{array}$

• Step 2: Add the rightmost column (Units).

Add the units digits: $6 + 9 = 15$. Place the 5 in the units column and carry over the 1 to the tens column.

• Step 3: Add the next column (Tens), including any carried-over value.

Add the tens digits and the carried-over 1: $3 + 7 + 1 = 11$. Place 1 in the tens column and carry over the 1 to the hundreds column.

• Step 4: Add the final column (Hundreds), including any carried-over value.

Add the hundreds digits and the carried-over 1: $9 + 1 = 10$. Since this is the leftmost column, write down the entire value as it is.

• Final sum:

The resulting sum is:

$\begin{array}{c} & 936 \\ + & 79 \\ \hline & 1015 \\ \end{array}$

Therefore, the correct answer is $1015$.
