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.

@SmartmanApps@dotnet.social I would argue that it's the same in base 12, it's just that 10 means something different. And no particular reason our 10 is any better or worse than base-12 10.
