When timetables are constructed by hand, the process is often 10% mathematics and 90% politics, [2] leading to errors, inefficiencies, and resentment among teachers and students." [1] For the simplest school timetable, such as an elementary school, these conditions must be satisfied: [3] a teacher cannot teach two courses in the same time slot
Depending on authors, the term "maps" or the term "functions" may be reserved for specific kinds of functions or morphisms (e.g., function as an analytic term and map as a general term). mathematics See mathematics. multivalued A "multivalued function” from a set A to a set B is a function from A to the subsets of B.
In mathematics, a multiplication table (sometimes, less formally, a times table) is a mathematical table used to define a multiplication operation for an algebraic system. The decimal multiplication table was traditionally taught as an essential part of elementary arithmetic around the world, as it lays the foundation for arithmetic operations ...
The Latin word data is the plural of datum, "(thing) given," and the neuter past participle of dare, "to give". [6] The first English use of the word "data" is from the 1640s. The word "data" was first used to mean "transmissible and storable computer information" in 1946. The expression "data processing" was first used in 1954. [6]

It is typically a graphic design showing a long bar labeled with dates alongside itself and (usually ...
The preceding kinds of definitions, which had prevailed since Aristotle's time, [4] were abandoned in the 19th century as new branches of mathematics were developed, which bore no obvious relation to measurement or the physical world, such as group theory, projective geometry, [3] and non-Euclidean geometry.

Francis Galton used the English term median for the first time in 1881 having earlier used the terms middle-most value in 1869 and the medium in 1880. [ 21 ] Adolphe Quetelet (1796–1874), another important founder of statistics, introduced the notion of the "average man" ( l'homme moyen ) as a means of understanding complex social phenomena ...
