[-x] + [y] - [-18j] X -[15 divided by L + x - y]

All the values can be what you want, but there are a few Guidelines.

x= Any negative number divisible by 11

BUT

y = x is x times 32

BUT

Y - X cannot equal any number that has the least common factor of 21

BUT

J = Any number divisible by 14 that is ALSO negative

BUT

L cannot equal x+y

BUT

L NEEDS to equal J times 13

BUT

J times 13 can not equal any number with the least common factor of 12.

Good luck, May the odds ever be in your favor.
