JAMES GRIME: There are people out there who want to change
the way that you count.
They want to change the world so that we stop counting using
10 symbols and start counting using 12 symbols.
I love them.
I think these guys are great.
Let's talk about what we know so far.
So, the way we count is the decimal system.
It uses 10 symbols.
So, let's just write those out, first of all.
0, 1, 2, 8, 9.
Once we get to this point, we start to have to make our
numbers using combinations of the symbols we've already got.
12, 13, 14, 22, 23.
Now, if we had been born with six fingers on each hand, then
we would have 12 fingers, and maybe we would have started
using something called the dozenal system where it's
based on 12 symbols.
And there are some people out there who think this is the
system we should be using.
They think we should have six fingers on each hand.
They're disappointed we don't have six fingers on each hand,
because they think it's a much easier way to count.
So first of all, if we're going to use 12 symbols, I
need two extra.
Let's have a look at what they suggest.
For 10, we we're going to have a symbol like this.
That's called dek.
And for 11, we're going to have a symbol like this, which
is called el.
So now it reads 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, dek, el.
This would be 12.
In fact, they say do.
So this is do, do 1, do 2, do 3, do 4, do 5, do 6, do 7, do
8, do 9, do dek, and do el.
