There are a set of common

notations for the use of various

radices. In

computing fields, numbers in

hexadecimal or preceded by 0x; numbers in

binary are preceded by 0b, and

octal numbers simply have a leading 0.

Mathematicians, on the other hand, prefer a more scalable notation system. Generally, numbers have a following subscript indicating a non-decimal base (e.g., 872_{9}), although more interesting systems, such as balanced ternary, can cause problems even here.
