Video Solution

Solution Steps

00:08 Let's solve the problem step by step.

00:11 Start by combining two digits at a time.

00:14 First, combine the ones with the ones.

00:18 Place the result in the ones column. Add one to the tens.

00:23 Next, combine the tens with the tens.

00:27 Add one to your calculation. Place the tens in the tens column.

00:31 Now, combine the hundreds with the hundreds.

00:35 Place the result in the hundreds column. Add one to the thousands.

00:39 Combine the thousands with the thousands.

00:42 Remember to add one to your calculation, then place it in the thousands.

00:47 Finally, combine and place the tens of thousands correctly.

00:51 Great job! That's how we find the solution.

Step-by-Step Solution

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

Now, let's work through each step:

Step 1: Align the numbers:
$\begin{array}{c} 19785 \\ +30406 \\ \hline \end{array}$

Step 2: Add the columns starting from the right:

Rightmost column (ones): $5 + 6 = 11$ . Write down $1$ , carry over $1$ .
Tens column: $8 + 0 = 8$ , plus the carry over $1$ gives $9$ .
Hundreds column: $7 + 4 = 11$ . Write down $1$ , carry over $1$ .
Thousands column: $9 + 0 = 9$ , plus the carry over $1$ gives $10$ . Write down $0$ , carry over $1$ .
Ten-thousands column: $1 + 3 = 4$ , plus the carry over $1$ gives $5$ .
Assembling these results, we have the sum of $50191$ .

Therefore, the solution to the problem is $\boxed{50191}$ .
