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

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

00:12 Combine tens with tens, remember to add 1 to the calculation

00:18 Place tens in tens

00:21 Combine hundreds with hundreds

00:26 Place hundreds in hundreds, and add 1 to thousands

00:31 Combine thousands with thousands, remember to add 1 to the calculation

00:34 Place thousands in thousands, and add 1 to tens of thousands

00:37 Combine tens of thousands with tens of thousands, add 1 to the calculation

00:43 Place in tens of thousands

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 $\boxed{50191}$ .
