    Using your fingers to count an sign is one of the best arguments in favor of the decimal system.
    For counting, one can easily use the thumbs to count on the other 12 falanges, with the actual benefitof visualizing halves, thirds and quarters.
    Signs for eleven and twelve are not so obvious.

    Dear Nathan,

    Have you ever considered being a software developer? I hear from my humans that it is good money and it is sometimes possible to work from home too. You might like it?

    Jct: Second big upgrade in math in recent years. Using a circumference based on Pi times the Diameter is bettered by basing it on Tau (double Pi) times the radius. Now, counting based on Ten is bettered by counting based on 12!!! Just have to do our counting in dozens!!! Maybe Inverts of Unity could be a third KISS breakthrough: http://SmartestManOnEarth.Ca/inverts

    Dear Nathan,
    Excellent tutorial. Your X and Z are much better than other symbols i’ve seen.
    I come from a time in England when used money was based on twelve. It was a difficult time to convert to decimal. Decimal to me has never seemed a good idea.
    Before decimalization on 15 February 1971, there were twenty (20) shillings per pound.

    The shilling was subdivided into twelve (12) pennies.

    The penny was further sub-divided into two halfpennies or four farthings (quarter pennies).

    2 farthings = 1 halfpenny
    2 halfpence = 1 penny (1d)
    3 pence = 1 thruppence (3d)
    6 pence = 1 sixpence (a ‘tanner’) (6d)
    12 pence = 1 shilling (a bob) (1s)
    2 shillings = 1 florin ( a ‘two bob bit’) (2s)
    2 shillings and 6 pence = 1 half crown (2s 6d)
    5 shillings = 1 Crown (5s)

    Denmark > koala > apple. I couldn’t think of another country beginning with D. And I figured most people would pick kangaroo, so I chose koala.

    Oh no! I’ve got to go out now but I started watching and kind of forgot the time. I’ll catch it later!

    haven’t watched till the end yet, but the mind trick at the beginning didn’t work for me. I had the words: Denmark, kea and apple (I’m a Dwarf Fortress player, so that’s probably what made the difference ;D)

    Thanks Nathan. Loved your presentation on the duedecimal system. Base numbering systems were taught when I was in 5th grade and as a ten year old, I loved it. Now at 65, I wish someone with your teaching ability would have been my math teacher. Well done!
