Re: [math-fun] A grid with MAX

Christian Boyer:

90134672 is my best score on 6x6:

I managed a 102568856 on my first manual try and 108885920 on my second, which may include, of course, arithmetical errors. I'm sure we're going to see better numbers. Because the manual arithmetic is such a pain, this would make a fun mobile app. On a reasonably large board (not necessarily square) you just keep tapping the next square in an attempt to beat your previous best.
