In Jess, parentheses always have special meaning; most of the time,
they mean "this is a function call". So (?slide) would mean "call what's in ?slide as a function", which is definitely not what you want. The "+" function, like all Jess functions, is called using prefix notation; the quantity "three more than ?slide" is written (+ ? slide 3) .
