Are you aware the historic (secular) use of the concept of zero?
Wiki says:
The first known English use of
zero was in 1598.
The
ancient Greeks had no symbol for zero (μηδέν), and did not use a digit placeholder for it.
[17] They seemed unsure about the status of zero as a number. They asked themselves, "How can nothing
be something?", leading to philosophical and, by the
medieval period, religious arguments about the nature and existence of zero and the
vacuum.
Transmission to Europe
The
Hindu–Arabic numeral system (base 10) reached Europe in the 11th century, via the
Iberian Peninsula through Spanish
Muslims, the
Moors, together with knowledge of
astronomy and instruments like the
astrolabe, first imported by
Gerbert of Aurillac. For this reason, the numerals came to be known in Europe as "Arabic numerals". The Italian mathematician
Fibonacci or Leonardo of Pisa was instrumental in bringing the system into European mathematics in 1202, stating:
After my father's appointment by his homeland as state official in the customs house of Bugia for the Pisan merchants who thronged to it, he took charge; and in view of its future usefulness and convenience, had me in my boyhood come to him and there wanted me to devote myself to and be instructed in the study of calculation for some days. There, following my introduction, as a consequence of marvelous instruction in the art, to the nine digits of the Hindus, the knowledge of the art very much appealed to me before all others, and for it I realized that all its aspects were studied in Egypt, Syria, Greece, Sicily, and Provence, with their varying methods; and at these places thereafter, while on business. I pursued my study in depth and learned the give-and-take of disputation. But all this even, and the algorism, as well as the art of Pythagoras, I considered as almost a mistake in respect to the method of the
Hindus (Modus Indorum). Therefore, embracing more stringently that method of the Hindus, and taking stricter pains in its study, while adding certain things from my own understanding and inserting also certain things from the niceties of Euclid's geometric art. I have striven to compose this book in its entirety as understandably as I could, dividing it into fifteen chapters. Almost everything which I have introduced I have displayed with exact proof, in order that those further seeking this knowledge, with its pre-eminent method, might be instructed, and further, in order that the Latin people might not be discovered to be without it, as they have been up to now. If I have perchance omitted anything more or less proper or necessary, I beg indulgence, since there is no one who is blameless and utterly provident in all things. The nine Indian figures are: 9 8 7 6 5 4 3 2 1. With these nine figures, and with the sign 0 ... any number may be written.

Here Leonardo of Pisa uses the phrase "sign 0", indicating it is like a sign to do operations like addition or multiplication. From the 13th century, manuals on calculation (adding, multiplying, extracting roots, etc.) became common in Europe where they were called
algorismus after the Persian mathematician al-Khwārizmī. The most popular was written by
Johannes de Sacrobosco, about 1235 and was one of the earliest scientific books to be
printed in 1488. Until the late 15th century, Hindu–Arabic numerals seem to have predominated among mathematicians, while merchants preferred to use the
Roman numerals. In the 16th century, they became commonly used in Europe.
