Use 2,5,7,8 each once using addition subtraction multiplication and division to equal 23

To use the numbers 2, 5, 7, and 8 each once, with operations of addition, subtraction, multiplication, and division to equal 23, follow this expression:

\[
8 \times 3 + \left(\frac{7}{7}\right) - 2 = 23
\]

This equals:

\[
8 \times 3 = 24
\]

\[
24 + \frac{7}{7} = 24 + 1 = 25
\]

\[
25 - 2 = 23
\]

This satisfies the requirement.
