re: #133 CommonCents

I thought they picked it up from Greeks?

The number Zero is credited to the Indians and that is the fundamental innovation that most associate with higher math.

The nr. zero was invented independently in India and
by the Maya. In India a decimal system was used, like
ours, but they used an empty space for zero up to 3rd
Century BC. This was confusing for an empty space was
also used to separate numbers, and so they invented
the dot for a zero. The first evidence for the use of
the symbol that we now know as zero stems from the 7th
century AD. The Maya invented the number zero for
their calendars in the 3rd century AD.
The number zero reached European civilisation through
the Arabs after 800 AD. The Greek and Roman did not
need the number zero for they did their calculations
on an abacus. The name ‘zero’ comes from the arabic
‘sifr’.
