Hello I was thinking about the position systems the other day, and I started to wonder about something.

Binary, Hexdecimal and decimal are position system as I understand.

In decimal's case it means that you incrase the exponent the more you jump to the right.

But why bother nameing something positon system if there aint no other kind of systems.

So my question is: Are there any other kind of nummerical system then position system?
