Did anyone invented 0, 1, 2 ?

Those are called number bases. Binary is base 2. What you describe is base 3. We commonly use base 10 or the decimal system. Programmers sometimes use hexadecimal which is base 16 and occasionally octal which is base 8.

The bottom line is you did not invent this. You might have recently discovered this for yourself but number bases have been around a long time.

Yes, I invented it before you.

Yes, for any set of values, it is generalized under the name of base.
Bases have been around for a few thousand years, and you are using bases every day.
degrees are base 360
minutes and seconds are base 60
hours are base 24
metric system is base 10
imperial system use base 12
computers are base 2

So chances that you invented something new is really tiny.
You probably rediscovered something by yourself.

0 - Wikipedia[^]

Machines only understand charged - 1 and discharged electrostatic semiconductor state - 0. So hence a binary code

Schrödinger invented the concept with his damned cat.

If anything, 0 was literally invented, which made number system more effective. The reason we use binary, because two state behavior that we can use in analog world. On and off.

As long as we understand number system that has zero, we are familiar with that.


If you search you will find many solution that can convert between any number system.

You may have "invented" it but I patented it.
