I’m not trying to pick a fight, really, but zero was discovered and not invented...imho.

a=b=1
aa=ab
aa-bb=ab-bb
(a+b)(a-b)=b(a-b)
a+b=b
2=1

The idea of “zero” was well known, but the actual representation of zero as a number had to be invented. We use Arabic numerals because their numbering system was so much easier to use and calculate with than the Roman or Greek numbering systems that used letters for numbers and quantities. The place holder numeral “zero” was indeed a great invention........

The argument about math concepts being invented or discovered is a great one and not yet settled!
