Can someone show me how to do math with the eval-expression tool? (+ 2 2) and such simple problems I can do of course but when it comes to combining things like: 52 * 32 / 12Trying (* 52 32 ( / 12))or (/ 12 ( * 52 32 )) Goes nowhere fast, and from there I can't really imagine how else to arrange the parens.
Just think "inner first" and watch for the argument order of course: (/ (* 52 32) 12)
