The expression \( -2^4 \) follows the order of operations (PEMDAS), where exponents are calculated before applying any signs. 

This means the expression is evaluated as:

\[
- (2^4)
\]

First, calculate the exponent:

\[
2^4 = 16
\]

Then apply the negative sign:

\[
- 16
\]

So, the value of \( -2^4 \) is:

\[
-16
\]
