Doesn't look better to me, just different.

Sigh. So you're yet another fraud.

I had mapped at 8.7% probability you might be legitimate.

Sucks to be me.

I start the topic with the creator of the Common Core math, his calculations of fractions mainly circulate among 2, 3, 4, 6, 8.

Too many Americans are standing against Common Core math programs, it's not that hard to learn. I feel it's easier to do the common core methods as it provides the ground for the fractional visualizations in the circles like the clock.

Clock is basically dozenal and the planet system is based on that also.

Imaging if the dozenal were the default math base, will people ever want to switch to decimal, most likely not.

I just keep placing more balls on the rows, red, orange, yellow, green, blue, purple. 4/3, 5/3, 2, 7/3, 8/3, 3.

I don't understand why base-12 advocates are so enchanted by the idea of bases in the first place. They don't really matter much at all; almost all of math is independent of base. I'm not opposed to changing our conventions, but base-16 would seem to bring more advantages. (You still get easy divisibility by 2, 3, and 5, plus all the advantages of binary, computing and otherwise.)

The divisions of hex are not easy in 3 or 5, it's easy in 2, 4 and 8. Dozenal is easy in 2, 3, 4, 6, sub-easy in 8, 9, 14(1 dozen 4), 16(1 dozen 6).

The math is only independent of the base if you count like the screenshots shown below.

Base 5 dozens can handle the fractions the best, but it has the cons that too many numerical symbols are involved even with the superbase in it(dozens in penta super base).

The width of the row is the base, I keep stack the balls, so the values of all the fractions are displayed accordingly, see the 1st screenshot below.

You seem overly concerned with fractions being "exact" for a small set of integer divisors.

Do you really want to return the £sd currency scheme?

Not with that currency, the currency with 0.01(penny), 0.04, 0.1(dime), 0.3(quarter), 1, 4, 10, 40, 100 where the multiples are of x4 and x3.

I want to be able to play "Windows Hearts" with only 3 players.

In the dozenal version of the Windows Hearts, there will be 2 more cards for each suit(spade, hearts, diamond, club), so 5 dozens total cards. Playable by 2, 3, 4, 5, 6 players at the best.

So now we are getting down to the real reason you like base-12: to play silly card game. That sounds like the best reason yet that you have presented so far. So let's do it.
