How did numbers and symbols came about?

Numbers and symbols developed as a means of quantifying and communicating information about the world. Early humans used tally marks and simple drawings to represent quantities, leading to more abstract concepts of numbers. Over time, various cultures created numeral systems, such as the Babylonian base-60 system and the Roman numeral system, which evolved into the modern decimal system we use today. Symbols emerged to represent these numbers, facilitating calculations and record-keeping, ultimately leading to the sophisticated mathematical systems we have now.
