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

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

00:09 We'll place the ones in ones, and add 1 to tens

00:17 Let's combine tens with tens

00:23 We'll place tens in tens, and add 1 to hundreds

00:26 Let's combine hundreds with hundreds

00:33 We'll place hundreds in hundreds, and add 1 to thousands

00:37 Let's combine thousands with thousands, remember to add 1 to the calculation

00:42 We'll place in thousands

00:48 Let's combine tens of thousands with tens of thousands, and place

Step-by-Step Solution

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

Now, let's work through each step:

Step 1: Arrange the numbers:

$\begin{aligned} &\phantom{+}81541 \\ + &\phantom{+}17759 \\ \end{aligned}$

Step 2: Add digits starting from the rightmost digit:

Units place: $1 + 9 = 10$ . Write down 0 and carry over 1.
Tens place: $4 + 5 = 9$ . Add the carried 1: $9 + 1 = 10$ . Write down 0 and carry over 1.
Hundreds place: $5 + 7 = 12$ . Add the carried 1: $12 + 1 = 13$ . Write down 3 and carry over 1.
Thousands place: $1 + 7 = 8$ . Add the carried 1: $8 + 1 = 9$ . Write down 9.
Ten-thousands place: $8 + 1 = 9$ . Write down 9.

The addition will look like this:

$\begin{aligned} &\phantom{8}81541 \\ + &\phantom{8}17759 \\ \hline &\phantom{8}99300 \\ \end{aligned}$

Therefore, the addition of these two numbers results in $99300$ .
