We count in base of 10 nowadays, while computer counts in base of 2 (binary) – do our ancient ancestors count in the same way?
Of course they don’t! 🙂
For example, ancient Babylonians used Sexagesimal (base 60) to count. How did they derive this base of 60? Well, it is based on how we count using our finger knuckles from one hand, and fingers from another hand – unlike we count using 10 fingers directly. It is weird, isn’t it?
Sexagesimal is still used in modern times. For example, there are 60 minutes in one hour, and 60 seconds in one minute. Another example is the sexagenary cycle in Chinese calendar.
