I’m curious how you could make that work as it’s a basic contradiction. For 6+6 to equal 10 6 couldn’t equal itself which makes the entire premise invalid.
If you want more single digit numbers hexadecimal aka base 16 is even better than 12. But I can’t see how 10 can be evenly divided by all of 2,3,4,6 without being a multiple of the set.
So how exes do they enforce this? Random dildo count inspectors? Dildo registration?
