(

L

?

Let's solve the expression step by step.

Given:
\[
J = 21
\]
\[
K = 1 - 8
\]
\[
L = 7 - 85
\]

First, calculate \( K \):
\[
K = 1 - 8 = -7
\]

Next, calculate \( L \):
\[
L = 7 - 85 = -78
\]

Now, calculate \( J - K \):
\[
J - K = 21 - (-7) = 21 + 7 = 28
\]

Finally, calculate \((J - K) \times L\):
\[
(J - K) \times L = 28 \times -78 = -2184
\]

So, the value of \((J - K) \times L\) is \(-2184\).
