The Coleman–Liau index is calculated with the following formula: = L is the average number of letters per 100 words and S is the average number of sentences per 100 words. The multiplication operator is often omitted in mathematical formulas when it is clear that multiplication is implied, but it is good practice to include it to avoid ...
Calculator spelling is an unintended characteristic of the seven-segment display traditionally used by calculators, in which, when read upside-down, the digits resemble letters of the Latin alphabet. Each digit may be mapped to one or more letters, creating a limited but functional subset of the alphabet, sometimes referred to as beghilos (or ...
In other words, a derangement is a permutation that has no fixed points. The number of derangements of a set of size n is known as the subfactorial of n or the n th derangement number or n th de Montmort number (after Pierre Remond de Montmort). Notations for subfactorials in common use include !n, D n, d n, or n¡ . [a] [1] [2]
For example, the number of distinct anagrams of the word MISSISSIPPI is: [38]!!!!! =. A k-permutation of a multiset M is a sequence of k elements of M in which each element appears a number of times less than or equal to its multiplicity in M (an element's repetition number).
Evidently, coincidences are more likely when the most frequent letters in each text are the same. The same principle applies to real languages like English, because certain letters, like E, occur much more frequently than other letters—a fact which is used in frequency analysis of substitution ciphers. Coincidences involving the letter E, for ...
The lexical density is the proportion of content words (lexical items) in a given discourse. It can be measured either as the ratio of lexical items to total number of words, or as the ratio of lexical items to the number of higher structural items in the sentences (for example, clauses).

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. Ancient Greeks used counting boards for numerical calculation and accounting, with a counter generically called psephos ('pebble'), analogous to the Latin word calculus , from which the English ...
