    Each finger is divided into 3 parts, tip, middle and base. You use your thumb on the same hand to count the finger part by touching it. Index tip is 1, middle finger tip is 4, ring middle is 8, pinkie base is 12.

    So using just one hand, you could keep count of say, bags of wheat that you’re handing to your customers with the other hand.

    Now bring your other hand into play, and you curl one finger into your fist each time you reach 12 on the other hand. 4 fingers plus the thumb is 5, 5*12 is 60.

    In theory you could go higher using finger segments on both hands, but the Babylonians liked the number 60, it had a lot of factors. Divides without remainders by 2, 3, 4 5, 6, 10, 12. That’s where we get 12 hour clocks from. 6*60=360, we get degrees of a circle. I could go on. 60 is just a really great number.

    Eye of Horus fractions are another really cool way to represent mathematical concepts in a single compact glyph.
