Can You Count in Base 12 or 20? 🧮⌚🐏

 Let's try this extracurricular activity.

We count in base 10, because we have 10 fingers on both hands, and it is easy to count so.

But it is not the only counting base used by people around the world.

1. We can count in DOZENS, on twelves.

12 hours in a day ⌚
12x2 = 24 hours in a day and night

12x5 = 60 - seconds in a minute
12x5 = 60 - minutes in an hour

Many people count eggs in dozens 🥚

12/2 = 6 - half-dozen

12x30 = 360 day, old year

Now let's use the base 12!

0           1           4           7           A
             2           5           8           B
             3           6           9           C

12 -> C
10 -> A
24 -> 20 - two-dozen
36 -> 30 - three-dozen
37 -> 31 - three-dozen and one

This is what is suggested the Sumerians counted like. They counted in base 12, probably using the phalanges of their fingers.

It is easy to count in base 12, because 12 is divisible by 2,3,4, and 6 - it has many factors.
