I was able to complete level 6 by causing division by zero (x=0). Are you sure it's not a bug?
P.S. Please, don't forget to inform your subscribers when you make new levels!
Hey if you like this game, I made my own version since this game seems to be abandoned :(
Thank you, I will try your game!
P.S.
I also noticed your clever design to avoid a level being solved due to division by zero!
