If you want a review of Mayan numbers and what we did in class, you can
look at what I wrote in class, and you can
check out these web sites:
Maya mathematics,
and Mayan
Math. There are lots of other web sites out there, but the
other web sites I looked at were doing things a bit differently than we
did in class in two ways:
--some web sites write the Mayan numbers horizontally. That's an
alternate way to write the numbers, but we only did the vertical
notation in class.
--some web sites use the place value variation 1-20-360 instead of
1-20-400. That is historically accurate, and how the Mayans
represented numbers when working with calendars. I'm not a Mayan
expert enough to tell you what's the best way to think about Mayan
arithmetic from a cultural perspective, but I'm a math teacher expert
enough to know that 1-20-400 is less confusing to teach and learn, so
that's what we're doing in this class, and what I expect you to know
how to do for this quiz.
