Let's solve the expression \( 23 - 8 \times 5 \).

According to the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), we perform multiplication first:

\[
8 \times 5 = 40
\]

Now, substitute back into the expression:

\[
23 - 40 = -17
\]

Thus, the result is:

\[
\boxed{-17}
\]
