The Arabic numerals I am referring to are “1234567890”. I have read that Thai numerals, “๑๒๓๔๕๖๗๘๙๐”, are actually distantly related. Both descend from the numeral system invented by the Phoenicians, which then developed into separate branches.
Is there a flow chart to show how the Thai numerals ended up as such? Why do both systems look so vastly different, when they are supposed to be based on the same “shape” given by the original Phoenician numerals?
