## digit- In mathematics, a digit is a symbol or numeral that is used to represent an integer in a positional number system.
Examples of digits include the decimal characters "0" through "9", the
binary characters "0" or "1", and the hexadecimal digits "0"..."9","A",...,"F."
The word comes from the Latin
*digitus*for finger or toe, and retains this meaning – reminding us of the origins of our base 10 number system. The earlier Indo-European root deik is related to many other words that hark back to the use of the hands and fingers to "point" out objects, including index, indicate, token, and teach.
• NUMBER THEORY - In anatomy, a digit is any part of the pentadactyl limb of vertebrates that contains a linear
