It is well known that we use the Decimal Numeral System just because we have ten fingers.

It is also well known that the numeral systems with base two and multiples of two make the calculations much easier, compared to the use of the decimal system.

Unfortunately we do not have an easy to use symbolgy for the most powerful numeral systems: we use part of the decimal symbols (binary and octal systems) or mixed decimal and alphabetic symbols (exadecimal system).

I propose the "Dexi Numeral System", a new exadecimal symbology where the symbols have a binary structure.

The system is very easy to learn and the calculations are made easier by the power of the exadecimal and binary systems.

Some operations are also "easy to see". Try, for example, to do a multiplication by two: you just need to shift to left all the segments of the original number.

The proposed system is, of course, just an amusing exercise but, maybe, in one or two millenia we will use something similar.
