I made a binary system for the digits 0 to 9.
I don't think that it is the regular binary system, but to me it seems to be better.
It can be used in either of two ways, as seen below, some might like one conversion more than the other.
-------------
0001 = 1 or 0
0010 = 2 or 1
0100 = 3 or 2
1000 = 4 or 3
1001 = 5 or 4
1010 = 6 or 5
1100 = 7 or 6
1101 = 8 or 7
1110 = 9 or 8
1111 = 0 or 9
-----------------
I am doing it all by hand, of course, so mistakes are possible.
One possible use for example: I will here use the first type of conversion.
These are real past draws of a pick 3 game from oldest below to newest on top.
204 = 0010-1111-1000 = 2121
932 = 1110-0100-0010 = 1220
577 = 1001-1100-1100 = 3201
431 = 1000-0100-0001 = 1101
468 = 1000-1010-1101 = 3111
237 = 0010-0100-1100 = 1210
625 = 1010-0010-1001 = 2021
296 = 0010-1110-1010 = 2130
127 = 0001-0010-1100 = 1111
I thought that I would make that system just in case anybody has a use for it.
