expression is made up of
(+ x y)
(- x y)
(* x y)
(/ x y)
(mod x const)
(lvl x y const)
(mix x y const)
You can mix & match different functions together, for example:
(+ (tan x) (cos y))
(+ (mod (* (sin y) const) (mod x y)) (well (+ (sin x) (sin y))))
(mod (avg x y) (mix (well y) (tent (cos (+ x const))) const))
