Learnt an interesting thing today on this arabic course,
The original Arabic number system looked like this, the one we now use.
It was designed so each character had the corresponding number of angles to the number, so the number 1 has 1 angle, 2 has 2 angles, 3 has 3, 0 has none etc…
It is so obvious now, I’ve always assumed its one of those things that just is, with no logical explanation, but here it is, perfectly simple and satisfying
My jaw is legit on the floor right about now :D
This is WRONG. COMPLETELY WRONG. I’ve seen this post on my dash at least ten times with no correction so here it is:
This is the evolution of the modern numeral system. PLEASE STOP SPREADING MISINFORMATION. The history of Mathematics is awesome and amazing and Arabs made tons and tons of progress and invented many of the concepts we use today, but a numeral system based on angles IS NOT ONE OF THEM.
