**Nonary** is a base 9 numeral system, typically using the digits 0-8, but not the digit 9. A numeral is a symbol or group of symbols that represents a number. ...
In mathematics and computer science, a numerical digit is a symbol, e. ...
The first few numbers in nonary and decimal are: `Nonary` | ` 1` | ` 2` | ` 3` | ` 4` | ` 5` | ` 6` | ` 7` | ` 8` | `10` | `11` | `12` | `13` | `14` | `Decimal` | ` 1` | ` 2` | ` 3` | ` 4` | ` 5` | ` 6` | ` 7` | ` 8` | ` 9` | `10` | `11` | `12` | `13` | The multiplication table in nonary is: ` *` | ` 1` | ` 2` | ` 3` | ` 4` | ` 5` | ` 6` | ` 7` | ` 8` | ` 1` | ` 1` | ` 2` | ` 3` | ` 4` | ` 5` | ` 6` | ` 7` | ` 8` | ` 2` | ` 2` | ` 4` | ` 6` | ` 8` | `11` | `13` | `15` | `17` | ` 3` | ` 3` | ` 6` | `10` | `13` | `16` | `20` | `23` | `26` | ` 4` | ` 4` | ` 8` | `13` | `17` | `22` | `26` | `31` | `35` | ` 5` | ` 5` | `11` | `16` | `22` | `27` | `33` | `38` | `44` | ` 6` | ` 6` | `13` | `20` | `26` | `33` | `40` | `46` | `53` | ` 7` | ` 7` | `15` | `23` | `31` | `38` | `46` | `54` | `62` | ` 8` | ` 8` | `17` | `26` | `35` | `44` | `53` | `62` | `71` | Nonary notation can be used as a concise representation of ternary data. This is similar to using quaternary notation for binary data, though the digit set is closer in size to octal. Ternary is the base 3 numeral system. ...
Quaternary is the base four numeral system. ...
The binary or base-two numeral system is a system for representing numbers in which a radix of two is used; that is, each digit in a binary numeral may have either of two different values. ...
The octal numeral system is the base-8 number system, and uses the digits 0 to 7. ...
Except for three, no primes in nonary end in 0, 3 or 6, since any nonary number ending in 0, 3 or 6 is divisible by three. 3 (three) is a number, numeral, and glyph. ...
A nonary number is divisible by two, four or eight, if the sum of its digits are also divisible by two, four or eight respectively. 2 (two) is the natural number following 1 and preceding 3. ...
4 (four) is the natural number following 3 and preceding 5. ...
8 (eight) is the natural number following 7 and preceding 9. ...
