.(1 point)
$$
Remaining Attempts : 3

Answer 1

To add the numbers \( 13.92 \) and \( -22.111 \), you can set it up as:

\[
13.92 - 22.111
\]

Now, let's align the decimal points and perform the subtraction:

\[
\begin{array}{r}
13.920 \\
- 22.111 \\
\hline
\end{array}
\]

Now, let's subtract:

1. From the rightmost column: \( 0 - 1 = -1 \) (we borrow 1 from the next column).
2. The next column (after borrowing): \( 2 - 1 = 1 \), so we write \( 1 \).
3. Move to the next column: \( 9 - 1 = 8 \).
4. Finally, the leftmost column: \( 3 - 2 = 1 \).

So when we do the calculation:

\[
\begin{array}{r}
13.920 \\
- 22.111 \\
\hline
-8.191 \\
\end{array}
\]

Thus,

\[
13.92 + (-22.111) = -8.191.
\]

The answer is \(-8.191\).
