Calculate the Sum: 847 Plus 77 in Vertical Format

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

• Step 1: Set up the addition problem vertically, aligning the numbers by their place values.
• Step 2: Add the digits column by column, starting from the rightmost position (units place).
• Step 3: If the sum in any column is 10 or more, carry over to the next column.

Now, let's work through each step:

Given numbers are:

$\begin{aligned} & 847 \\ + & \phantom{} 77 \\ \end{aligned}$

Step 1: Start with the units place.

$7 + 7 = 14$. Write down 4 in the units place, and carry over 1 to the tens place.

Step 2: Move to the tens place.

$4 + 7 = 11$, plus the carried over 1 makes it 12. Write down 2 in the tens place, and carry over 1 to the hundreds place.

Step 3: Finally, add the hundreds place.

$8 + 0 = 8$, plus the 1 carried over makes it 9. Write down 9 in the hundreds place.

The sum is:

$\begin{aligned} & 847 \\ + & \phantom{} 77 \\ \hline & 924 \\ \end{aligned}$

Therefore, the solution to the problem is $924$.
