Given the current instructions and considering the format and clarity of the original mathematical expression, I will provide a well-structured version of the task. However, the original expression seems to lack context or specific instructions. I will assume it's an arithmetic operation needing evaluation.

Evaluate the following expression:

[tex]\[
\begin{array}{r}
30 + 30 \\
- 40 \\
\times 80 \\
\hline
\end{array}
\][/tex]

Certainly! Let's solve the problem step-by-step.

1. Addition: Start by adding 30 and 30 together.
[tex]\[ 30 + 30 = 60 \][/tex]

2. Subtraction: Take the result from the addition and subtract 40.
[tex]\[ 60 - 40 = 20 \][/tex]

3. Multiplication: Finally, take the result from the subtraction and multiply it by 80.
[tex]\[ 20 \times 80 = 1600 \][/tex]

So, the detailed step-by-step results are:

1. [tex]\( 30 + 30 = 60 \)[/tex]
2. [tex]\( 60 - 40 = 20 \)[/tex]
3. [tex]\( 20 \times 80 = 1600 \)[/tex]

Thus, the results of the operations are:

- After addition: 60
- After subtraction: 20
- After multiplication: 1600
