A numeral system (or system of numeration) is a writing system for expressing numbers, that is, a mathematical notation for representing numbers of a given set, using digits or other symbols in a consistent manner. It can be seen as the context that allows the symbols "11" to be interpreted as the binary symbol for three, the decimal symbol for eleven, or a symbol for other numbers in different bases.
The number the numeral represents is called its value.
Ideally, a numeral system will:
For example, the usual decimal representation of whole numbers gives every non zero whole number a unique representation as a finite sequence of digits, beginning by a non-zero digit. However, when decimal representation is used for the rational or real numbers, such numbers in general have an infinite number of representations, for example 2.31 can also be written as 2.310, 2.3100000, 2.309999999..., etc., all of which have the same meaning except for some scientific and other contexts where greater precision is implied by a larger number of figures shown.

An introduction to number systems, and how to convert between decimal, binary and hexadecimal numbers
What are the number systems ? Number systems are the technique to represent numbers in the computer system architecture, every value that you are saving or getting into/from computer memory has a defined number system. Computer architecture supports following number systems. Binary number system Octal number system Decimal number system Hexadecimal (hex) number system Binary number system A Binary number system has only two digits that are 0 and 1. Every number (value) represents with 0 and 1 in this number system. The base of binary number system is 2, because it has only two digits. Octal number system Octal number system has only eight (8) digits from 0 to 7. Every number (value) represents with 0,1,2,3,4,5,6 and 7 in this number system. The base of octal number system is 8, becaus...

"In mathematics and digital electronics, a binary number is a number expressed in the binary numeral system or base-2 numeral system which represents numeric values using two different symbols: typically 0 (zero) and 1 (one). The base-2 system is a positional notation with a radix of 2. Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used internally by almost all modern computers and computer-based devices. Each digit is referred to as a bit." Wikipedia Link So basically Binary is the little 1's and 0's we all have seen and heard about, that a CPU understands. This is how a CPU determines what to do based on sequences of one's and zero's, 1 being "ON" and 0 being "OFF". we can Easily take binary and translate it into E...
About 7,000 years ago our trading ancestors took the first steps in developing the prototypes of an alphabetical system and a numeral system. Of the two, our ancestors may have needed numbers before letters but the beginning of organised trade required both systems. For the first time in probably 40,000 years it was possible for information and experiences to be transferred from the elusive memory of the human mind to more durable surfaces. Trade needs both letters and numbers to function and most activities in markets involve documentation, calculation and the issue of receipts for goods bought and sold. The bond between letters and numbers has been historically strong, a subject which was treated in other videos, but in this video, we are including original etymological research to suppo...
*The Arabian Nights Numeric Wonder*: The Arabic Numerals System is a gift of human ingenuity like no other and like no other its simplicity, accuracy and effectiveness. There is something magical about numbers and numerals. Like the flying carpet of the Arabian Nights, even the greatest numbers we can think of are processed with astonishing speed. If people can find the word to name a new high number, the Arabic Numeral System will produce its entire numerals before they finish. Subconsciously, it occurred to this writer and his colleagues, we’ve always known that the numerals are reproductions of things we have affinity with but it took some time before realising our hands and fingers are the numerals. This video is one of a series of 10 shows covering almost every aspect of the numerals ...
The Twining of Arabic and Europeans Numerals: This video is presented as part of everything important that needs to be known about the origin, history, development, usage and the dissemination of numbers and the Arabic Numerals System from an authority on the origin of the Arabic Numerals and their positional system. The main theme of the video are the steps taken to insure the provision of an adapted family of the Arabic Numerals and their system to European users beginning in the 12th century. When the twined set of Arabic Numerals were finalised Europeans had the chance to begin their application for scripts that run from left to right. The impact of the introduction of Arabic Numerals to Europe cannot be underestimated for its contribution to European Renaissance and further dissemina...
In this computer science short, I explain how different numbering systems exist. Principally the familiar decimal system is explained, followed by binary and hexadecimal number systems which are useful in computer programming. I briefly touch on Sexagesimal and Duodecimal systems too.

The Hindu-Arabic number system is the most important single advance in the history of science and mathematics. In this video we start from a naive Kindergarten approach to numbers, and then move to a simplified Roman numeral system, as a stepping stone to the Hindu-Arabic system. Along the way we introduce the usual names and symbols for the numbers 1-9, mention the big role that the number zero (0) plays, and discuss the world's earliest and most popular calculator---the abacus.
