If K = 1, 2 then it will be X(i,j,1,l,m,n) + X((i,j,2,l,m,n)
I'm confused what does Kl means? How do you input Kl to the equation?

What do "dari" and "dan" mean? And what do K1 and K2 mean, with superscripts rather than subscripts?

But it appears that Kl means the set of students of a teacher named l.

We really need to see the definitions of all the sets (K, M, N); and the wording of the definition of Kl confuses me, as I would have thought K, not k, is a set. Did you copy the statement exactly as given to you?
