To solve the expression \( 24 \div 2^3 - 4 \times 5 \), we will follow the order of operations (often remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).
1. **Exponents**: Calculate \( 2^3 \).
\[
2^3 = 8
\]
2. **Division**: Now, divide \( 24 \) by \( 8 \).
\[
24 \div 8 = 3
\]
3. **Multiplication**: Next, calculate \( 4 \times 5 \).
\[
4 \times 5 = 20
\]
4. **Subtraction**: Now we substitute back into the expression:
\[
3 - 20
\]
5. Finally, perform the subtraction:
\[
3 - 20 = -17
\]
So, the result of the expression \( 24 \div 2^3 - 4 \times 5 \) is \( \boxed{-17} \).
