You only have to go as far as you want, of course. If you want to go up to A * A, fine. If you want to go to C * C, great. There's no reason to go to precisely 10 * 10 in the given base.

This might have been the reason why hex wasn't popular outside the computerized professions. Some Spanish speaking natives will likely mix the 2 up. Last fiddled with by tuckerkao on 20200813 at 14:14

Hey tweedledee, how much is 6*4? I dunno tweedledumb, how much is 6*4? No, it is a real question, how much is 6*4? Are you kidding me? That is for those advance nerdbrains to know, not normal ingroup people like us. So moving on, what's been trending in the last 5 seconds?

Fortunately, the mathematics doesn't care one whit what you think it's like. If you decide to work in ternary you're not restricted to teaching the times tables up to 3, and if you work in sexigesimal you don't need to memorize times tables up to 60. There are lots of ways to do things.
Of course if you wanted to teach a full times table, you could use octal just as easily, but that's beside the point. Last fiddled with by CRGreathouse on 20200813 at 14:21

For Dozenal multiplication tables: 2, 3, 4, 6 are easy. 8, 9, Ɛ are medium, only 5, 7 and Ӿ are hard. Dozenal 7 times table is actually easier than Decimal 6 times(on the odds) table if you know both bases equally well. Like what retina said, Dozenal as the default math base won't leave behind the kids behind. Last fiddled with by tuckerkao on 20200813 at 14:56

So, by your logic English letters B, C, D, E, G, P, T, and Z should have different names because people can mishear them.

People were using numbers before the concept of a base (radix) was even invented. And the idea that numbers can "speak for themselves" was not unknown to them.

Any user of a base needs to know the multiplication table for all units. Anything less and you can't do the math. Base 60 systems are generally a compound base of 12 and 5.

Except when they are not.
I gave a specific example which was in widespread use for well over two thousand years. Remnants of it are still in widespread use well after four thousand years. It is a combination of base 6 and base 10. I type this from 28°38'30" N 17°52'04" W. Last fiddled with by xilman on 20200813 at 18:39 Reason: s/write/type/
