Well by that logic if you have nothing, there's nothing you can do to it, so you will always have nothing, which reconciles quite nicely with multiplying numbers by 0 resulting in 0.

Q: "How many times has it rained this week?"

A: "It has rained zero times"

Zero is a perfectly natural state.


I think humans could predict solar eclipses and solve quite a few differential equations before they managed to give that answer. The normal answer to that question was “It hasn’t rained this week” or even “What do you mean? It hasn’t rained this week”.

https://en.wikipedia.org/wiki/Brahmagupta#Zero: ”The Brāhmasphuṭasiddhānta is the earliest known text to treat zero as a number in its own right, rather than as simply a placeholder digit in representing another number”

That book is from around AD 628 (https://en.wikipedia.org/wiki/Brāhmasphuṭasiddhānta)
