Well yeah, that's what we started out with, because more factors. Not sure if you realised, but we have 360 degrees in a circle because NEARLY 365 (like in days per year) BUT has a lot more factors than 365 (because 360 is a multiple of both 12 and 10).

@dm319@fosstodon.org But having said that, Base Ten works really well for mental arithmetic, cos just add a zero to multiply by 10. So for example to multiply by 30 I just need to multiply by 3 and then add a zero - done! To multiply by 9, then just add a zero and subtract the thing you're multiplying. e.g. 9x15=10x15-1x15=150-15=135.
