To express any number, it suffices to enumerate the (hexadecimal) digits that make it up. For example: the number written as "2000" in decimal, which translates to "7D0" in conventionally-written hexadecimal, would in Bibi-binary be spoken aloud as "BIDAHO".

Contrary to the numeric conventions used in modern computers, the bibi-binary system represents negative numbers using [[ones' complement]],{{citation needed|date=October 2016}} rather than [[two's complement]]. Thus:
* +7 is written 0 0111
* −7 is written 1 1000
and their sum is written as "1 1111" (one of two representations of zero in this system; zero can also be written as "0 0000").
On modern machines, in classic binary notation, −7 would be written 1 1001, and the sum of −7 and 7 would give "0 0000"; this "two's complement" system thus needs only a single representation for the number zero.
