Sounds like we are confusing cardinal with ordinal.

There is no 0 on a ruler.

There is no year 0.

They are not Zeroth Sequences.

For starters – some history of the Glyph that we refer to as Zero, and the concept of the Zero and the place holder (that we use the glyph for) are three different things.

Early Babylonians used a place holder, but ‘zero’ was not used in calculations.

The Greeks did not adapt the Babylonian number system, and had no positional number system. Greek mathematical advances were essetally based on Euclid’s “Elements”…it’s all based on geometry. BTW – there is no 0 degree angle.

Greek astronomers used the glyph that we would recognize as zero in the recording of astronomical data. There are numerous explanations, that it stood for ‘Ouden” or “Obol”. The usage did not stick around.

Ptolemy, in “Almagest” (130 AD) uses the Babylonian base sixty system and their ‘place-holder’ concept. Sorta Kinda. Ptolemy did not think of it as a number or a concept, but as a punctuation mark. Kind of like a period.

In India, the Hindu word for zero was ‘shunya’, or ‘sunya’ meaning ‘void’. This was translated into Arabic as ‘sifr’, and into English as ‘Cypher’.

Mohammad ibn Mus al-Kwarizmi (ce 780-850) was a mathimatician who introduced Hindu Arabic numerals, his book “Kitab al-jabr wa al-mugabalah” influenced these concepts when it was translated in the 12th Centruy.

In 1202, Leonardo of Pisa (or Leonardo Fibonacci – of whom I have posted about on more than one occaision) explained the concept of positional base notation, the point, negative numbers, and the zero, in his book, “Book of Abacus.”

However he speaks of the ‘sign’ zero rather than the number zero. And the ‘Fibonacci Sequence’ that kept scholars amused for hundreds of years is not (surprise surprise) a zeroth sequence – although one needs to grasp the concept of zero as a place holder and an abstract concept to fully grasp the enormity of the sequential implications. (they are still writing books on the Fibonacci Sequence, and the Golden Mean).

None of these concepts (or zero) were widely used, or accepted until the 17th Century, and even then experienced resistance.

The Glyph that we refer to as Zero, came from India and in Arabic is called ‘galgal’, or “Wheel”.

The Arabic Glyph for zero is ‘"’.

Seriously folks. A little research, a little history.

We have the following subjects on Zero.

Zero as a concept

Zero as a placeholder (4 Tarot Cards or 4 things is different then the abstract concept of ‘Four”).

Zero – the Glyph used to illustrate it.

01234 & 1234 are indeed, mathematically, conceptually, historically, very very different things.
