00:03 Each time we consider combining 2 digits, and then we'll place

00:06 Let's start by combining ones with ones

00:09 Place the ones, add 1 to the tens

00:16 Combine tens with tens, remember to add 1 to the calculation

00:24 Place tens in tens, add 1 to hundreds

00:30 Combine hundreds with hundreds, remember to add 1

00:35 Place hundreds in hundreds, and add 1 to thousands

00:39 Place 0 in the missing digits

00:42 Combine thousands with thousands, remember to add 1

00:45 Place in thousands

Step-by-Step Solution

To solve this problem, we will perform the addition of the numbers 877 and 656 using the vertical column method. Let's break it down step by step:

Step 1: Write the numbers vertically aligned by their place values: units, tens, and hundreds.
Step 2: Start by adding the units column (rightmost column): $7 + 6 = 13$ . Write down 3 in the units place and carry over 1 to the tens place.
Step 3: Next, add the tens column: $7 + 5 = 12$ . Adding the carryover 1 gives total $13$ . Write down 3 in the tens place and carry over 1 to the hundreds place.
Step 4: Finally, add the hundreds column: $8 + 6 = 14$ . Adding the carryover 1 gives total $15$ . Since this is the leftmost column, write down the entire result, 15, in the appropriate place.

The sum of the numbers is therefore $1533$ .

Hence, the correct answer to the problem is $1533$ .
