...so anyways, I'm annoyed by this puzzle because THERE ARE 2 SOLUTIONS TO IT!!!
the last entry 9 _ 1 can be either a multiply or a DIVIDE!! I kept putting a divide in there and always got it incorrect. I thought this was jsut another bug until reading forums and realized I should have used "*".
I felt silly that i didnt think of the simpler product, but using divide is a valid expression that mathematically results in the same conclusion.
... of course I can't go back there (yet??), because I told the mandalorian to continue out.
