In mathematics, a variable (from Latin variabilis, "changeable") is a symbol, typically a letter, that refers to an unspecified mathematical object. [1] [2] [3] One says colloquially that the variable represents or denotes the object, and that any valid candidate for the object is the value of the variable. The values a variable can take are ...
A one-letter word is a word composed of a single letter. The application of this apparently simple definition is complex, due to the difficulty of defining the notions of word and letter. One-letter words have an uncertain status in language theory, dictionaries and social usage.
Historically, upper-case letters were used for representing points in geometry, and lower-case letters were used for variables and constants. Letters are used for representing many other types of mathematical object. As the number of these types has increased, the Greek alphabet and some Hebrew letters have also come to be used.
These tables show all styled forms of Latin and Greek letters, symbols and digits in the Unicode Standard, with the normal unstyled forms of these characters shown with a cyan background (the basic unstyled letters may be serif or sans-serif depending upon the font).
Random variables are usually written in upper case Roman letters, such as or and so on. Random variables, in this context, usually refer to something in words, such as "the height of a subject" for a continuous variable, or "the number of cars in the school car park" for a discrete variable, or "the colour of the next bicycle" for a categorical variable.
Ever since the Babylonian exile, some mystics have explained a word or group of words by the numerical value of its letters, and by comparison with another word of the same value. Alef = 1, dalet = 4, etc. According to Gikatella (14th century), the word Echad, "One", is equivalent to the word Ahabah, "Love
Letters are typically used for naming—in mathematical jargon, one says representing—mathematical objects. The Latin and Greek alphabets are used extensively, but a few letters of other alphabets are also used sporadically, such as the Hebrew , Cyrillic Ш, and Hiragana よ. Uppercase and lowercase letters are considered as different ...
' pebble ') or isopsephism is the practice of adding up the number values of the letters in a word to form a single number. [1] The total number is then used as a metaphorical bridge to other words evaluating the equal number, [2] which satisfies isos or "equal" in the term.
