I replaced each even digit with * and each odd with _ to show the solution.
*___*__**__***_*__*
**_**_*__*__*__*__*
*_*_*_****__*__****
*___*_*__*__*__*__*
*___*_*__*__*__*__*
Math (spelled out with even digits.)
So maybe we aren't the odd ones.
I have a little more to say about the origin of this problem, see my note in the forums. http://perplexus.info/forum.php?fid=3&tid=729#5118 |
