The following table lists many specialized symbols commonly used in modern mathematics, ordered by their introduction date. The table can also be ordered alphabetically by clicking on the relevant header title.
This quarter system was adopted by the oldest universities in the English-speaking world (Oxford, founded circa 1096, [1] and Cambridge, founded circa 1209 [2]). Over time, Cambridge dropped Trinity Term and renamed Hilary Term to Lent Term, and Oxford also dropped the original Trinity Term and renamed Easter Term as Trinity Term, thus establishing the three-term academic "quarter" year widely ...

Commonly used for denoting any strict order. 3. Between two groups, may mean that the second one is a proper subgroup of the first one. ≤ 1.
This is a timeline of pure and applied mathematics history.It is divided here into three stages, corresponding to stages in the development of mathematical notation: a "rhetorical" stage in which calculations are described purely by words, a "syncopated" stage in which quantities and common algebraic operations are beginning to be represented by symbolic abbreviations, and finally a "symbolic ...
The term was coined when variables began to be used for sets and mathematical structures. onto A function (which in mathematics is generally defined as mapping the elements of one set A to elements of another B) is called "A onto B" (instead of "A to B" or "A into B") only if it is surjective; it may even be said that "f is onto" (i. e ...
The last quarter of the year is the fourth quarter or Q4. This quarter takes place in October, November and December. Q4 is the time when most companies have to hustle.
Use the median to divide the ordered data set into two halves. The median becomes the second quartile. If there are an odd number of data points in the original ordered data set, do not include the median (the central value in the ordered list) in either half.
