3$\begingroup$ If your test is that arithmetic is "scientific" then numerology definitely precedes it since science emerged along with Pythagoreans. But it is more accurate to say that practical and playful/ritualistic uses of numbers developed in parallel, sometimes inseparably, see e.g. I Ching or Babylonian astrology. For prehistoric arithmetical artifacts see hsm.stackexchange.com/questions/3334/… $\endgroup$Conifold– Conifold2017-01-24 02:35:38 +00:00Commented Jan 24, 2017 at 2:35

1$\begingroup$ Numerology is alive and well still today. There are lot of people trying to discover "deep meaning" into numbers. In ancient civilizations, the first speculations about numbers mixed purported "deep meaning" with "scientific" arithmetical meaning (e.g. the property of being prime) of numbers. $\endgroup$Mauro ALLEGRANZA– Mauro ALLEGRANZA2017-01-24 09:53:32 +00:00Commented Jan 24, 2017 at 9:53

$\begingroup$ @Conifold Thanks for the paleolithic ink! Right now I'm working on a combinatorial game, and found this cave etching to be quite compelling, because it's on the floor as opposed to a wall (i.e. raising at least the possibility it could have been a gameboard.) Interesting point is that, in developing a novel set of combinatorial game mechanics, it was the application of metaphors to integers that provided the key insight, not mathematics per se. $\endgroup$DukeZhou– DukeZhou2017-01-24 19:53:27 +00:00Commented Jan 24, 2017 at 19:53

$\begingroup$ @MauroALLEGRANZA I find it interesting that mystical terms are still being applied to mathematical concepts, such as with transcendental numbers. I also know that Cantor's work on infinite sets, for instance, carried philosophical as well as mathematical implications. $\endgroup$DukeZhou– DukeZhou2017-01-24 19:54:01 +00:00Commented Jan 24, 2017 at 19:54

2$\begingroup$ I wonder if there is a record of some number-theoretic properties discovered in the course of practicing numerology. On the other hand, Gematria-- a numerological system based on the Hebrew alphabet-- developed some pretty sophisticated techniques using what we would call recursive procedures, permutations, substitutions etc. See en.wikipedia.org/wiki/Gematria So one could argue that numerology is a precursor to combinatorics. $\endgroup$Margaret Friedland– Margaret Friedland2017-01-25 18:12:38 +00:00Commented Jan 25, 2017 at 18:12

How to Edit
- Correct minor typos or mistakes
- Clarify meaning without changing it
- Add related resources or links
- Always respect the author’s intent
- Don’t use edits to reply to the author
How to Format
-
create code fences with backticks ` or tildes ~
```
like so
``` -
add language identifier to highlight code
```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- quote by placing > at start of line
- to make links (use https whenever possible)
<https://example.com>[example](https://example.com)<a href="https://example.com">example</a>
- MathJax equations
$\sin^2 \theta$
How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. reference-request), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
