To solve the problem of adding the two numbers, [tex]\( 8.260439 \)[/tex] and [tex]\( 11 \)[/tex], follow these steps:
1. Identify the given numbers:
[tex]\[ 8.260439 \][/tex]
[tex]\[ 11 \][/tex]
2. Align the decimal points:
When adding numbers with decimals, it's important to align the decimal points vertically to ensure each digit is correctly positioned according to its place value.
[tex]\[
\begin{array}{r}
8.260439 \\
+ 11.000000 \\
\hline
\end{array}
\][/tex]
3. Add the numbers digit by digit:
Start adding from the rightmost column of digits and move towards the left, carrying over if necessary.
4. Add the fractional part of the numbers:
Since [tex]\( 11 \)[/tex] has no fractional part, you can consider it as [tex]\( 11.000000 \)[/tex] while aligning the decimal points for addition.
[tex]\[
8.260439 + 0.000000 = 8.260439

5. Add the integer parts:
[tex]\[
8 + 11 = 19
\][/tex]
6. Combine the integer part and the fractional part:
[tex]\[
19 + 0.260439 = 19.260439
\][/tex]
Therefore, the sum of [tex]\( 8.260439 \)[/tex] and [tex]\( 11 \)[/tex] is:
[tex]\[
19.260438999999998
\][/tex]
