   Everyday Mathematics. Everyday Mathematics is a pre-K and elementary school mathematics curriculum, developed by the University of Chicago School Mathematics Project (not to be confused with the University of Chicago School of Mathematics). The program, now published by McGraw-Hill Education, has sparked debate.

3. Net (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Net_(mathematics)

   Net (mathematics) In mathematics, more specifically in general topology and related branches, a net or Moore–Smith sequence is a function whose domain is a directed set. The codomain of this function is usually some topological space. Nets directly generalize the concept of a sequence in a metric space. Nets are primarily used in the fields ...

   en.wikipedia.org/wiki/Mathematics

   Mathematics is a field of study that discovers and organizes methods, theories and theorems that are developed and proved for the needs of empirical sciences and mathematics itself. There are many areas of mathematics, which include number theory (the study of numbers), algebra (the study of formulas and related structures), geometry (the study ...

5. Sequence - Wikipedia

   Sequence. An infinite sequence of real numbers (in blue). This sequence is neither increasing, decreasing, convergent, nor Cauchy. It is, however, bounded. In mathematics, a sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

   Recamán's sequence: 0, 1, 3, 6, 2, 7, 13, 20, 12, 21, 11, 22, 10, 23, 9, 24, 8, 25, 43, 62, ... "subtract if possible, otherwise add": a(0) = 0; for n > 0, a(n) = a(n − 1) − n if that number is positive and not already in the sequence, otherwise a(n) = a(n − 1) + n, whether or not that number is already in the sequence.

7. Telescoping series - Wikipedia

   en.wikipedia.org/wiki/Telescoping_series

   In mathematics, a telescoping series is a series whose general term is of the form , i.e. the difference of two consecutive terms of a sequence . As a consequence the partial sums of the series only consists of two terms of after cancellation. [1][2] The cancellation technique, with part of each term cancelling with part of the next term, is ...
