Or we could use binary

Or we could look at why our ancestors uses 12 as a base?

The reason is Pythagorean. And the fact that our numbering system is based upon counting right angles

If you draw one right angle it represented one in a way anybody could understand. Add another line and you get a zig zag that easily morphed into a 2

Add yet another line and you get a recognisable 3

Four was depicted by a cross.

Eight was an easy two squares one on top of the other.

Nine was the above with a tail added.

The in between numbers varied a bit but the premise was always count the right angles. Hence a zero. Nought has no angles an so = nothing.

But why use base 12?

A ruler had 12 inches - and so made it easy to make a right angled triangle 3”, 4”, and 5”. Total 12”. Make a triangle of those three lengths and you always have a right angle.

So, want to build a wall? Then such a device helps set the floor level and the wall vertical.

History has some interesting facts to teach us
