Video Solution

Solution Steps

00:04 Let's solve this problem step by step.

00:07 First, combine two digits at a time. Ready?

00:11 Start by adding the ones digits together.

00:15 Place the result in the ones place. Remember to carry 1 to the tens.

00:21 Now add the tens digits. Don't forget to add that 1.

00:27 Put the result in the tens place. Carry 1 more to the hundreds.

00:34 Make sure 0 is in any missing places.

00:38 Finally, add the hundreds digits. Add that 1. Place in hundreds.

00:43 Great job! That's how we solve the question.

Step-by-Step Solution

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 $924$ .
