Solution Steps

00:06 Let's solve the problem by combining numbers step-by-step.
00:10 Start by pairing two digits at a time. It helps keep things neat.
00:15 First, combine the ones digits. Ready?
00:19 Add the ones, and place them. Don't forget to carry one to the tens.
00:25 Now, focus on the tens digits. Add them up, plus the carried one.
00:30 Place the sum in the tens column, and carry one to the hundreds.
00:35 Next, add the hundreds digits, including the carried one.
00:40 Place the sum in the hundreds column.
00:43 Great job! That's how you solve this problem.

Step-by-Step Solution

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

  • Step 1: Align the numbers 728728 and 182182 vertically by their respective place values (ones, tens, hundreds).

  • Step 2: Add the digits in each column starting from the ones place and moving to the left (tens, then hundreds), carrying as necessary.

Now, let's work through each step:
Step 1: The numbers are aligned as follows:

amp;7amp;2amp;8+amp;1amp;8amp;2 \begin{array}{c} & 7 & 2 & 8 \\ + & 1 & 8 & 2 \\ \hline \end{array}

Step 2: Start adding from the rightmost column (ones):

8+2=108 + 2 = 10. We write down the 00 and carry over the 11 to the tens column.

Next, add the tens column including the carried 11:

2+8+1=112 + 8 + 1 = 11. We write down the 11 and carry over the 11 to the hundreds column.

Finally, add the hundreds column including the carried 11:

7+1+1=97 + 1 + 1 = 9. Write the 99.

Therefore, the sum is 910910.

The solution to the problem is 910\boxed{910}.

Answer

910
