A list of articles about numbers (not about numerals). Topics include powers of ten, notable integers, prime and cardinal numbers, and the myriad system.
This list gives those most commonly encountered with Latin script. For a far more comprehensive list of symbols and signs, see List of Unicode characters. For other languages and symbol sets (especially in mathematics and science), see below
A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula.
The total number of distinct Egyptian hieroglyphs increased over time from several hundred in the Middle Kingdom to several thousand during the Ptolemaic Kingdom. In 1928/1929 Alan Gardiner published an overview of hieroglyphs, Gardiner's sign list, the basic modern standard. It describes 763 signs in 26 categories (A–Z, roughly).
"A base is a natural number B whose powers (B multiplied by itself some number of times) are specially designated within a numerical system." [1]: 38 The term is not equivalent to radix, as it applies to all numerical notation systems (not just positional ones with a radix) and most systems of spoken numbers. [1]

The main chart includes only consonants with a single place of articulation.
It was not until the Middle Ages that the letter W (originally a ligature of two V s) was added to the Latin alphabet, to represent sounds from the Germanic languages which did not exist in medieval Latin, and only after the Renaissance did the convention of treating I and U as vowels, and J and V as consonants, become established.
The nnnn or hhhh may be any number of digits and may include leading zeros. The hhhh may mix uppercase and lowercase, though uppercase is the usual style. In contrast, a character entity reference refers to a character by the name of an entity which has the desired character as its replacement text.
