circular calculator and clock

I was looking for "low cognitive load" calculators, meaning that the kid does not need even to look for the "=" or "*" signs when asking for a multiplication. 

It was not easy to find one, so I vibe coded a set of layouts to check out. At the end it seems one needs a circular layout to swipe multi-digit numbers. Not a surprise that Gboard does not support swipe for numbers. 

I found it was a problem for large numbers because people accidentally raises the finger when looking for the next digits, so the most detailed versions allow "swipe continuation": 

- if one starts from the numerical keys, it is a new number 

- if the finger starts from outside the keyring, it is a continuation
