I googled around a while last night, and they ahd sort of a
hybrid notation.  The Sumerians started withindividual "tic
marks" up to 9, and symbols for 10, 60, 600, 3600 and so on.
That evolved into the Babylonian base-60 position-weighted
system (without a zero symbol) that used only the 1 symbol and
the 10 symbol.

And 60 seconds in a minute, 60 minutes in a hour (for both time
and angles), and 60 minutes in a degree.
