  2. Inequality (mathematics) - Wikipedia

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

    The feasible regions of linear programming are defined by a set of inequalities.. In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. [1]

  3. Cram school - Wikipedia

    en.wikipedia.org/wiki/Cram_school

    Students in CPGE have between 36 and 40 hours of class a week, as well as one or more weekly 2-to-4 hours written test on each major (often also on Saturday). Students are expected to work on their own at least 2 hours a day, while the most ambitious students can work more than 5 hours every evening after classes, as well as during the weekend ...

  4. Tower of Hanoi - Wikipedia

    Move 255 10 (2 8 − 1) = 11111111. The largest disk bit is 1, so it is on the final peg (2). All other disks are 1 as well, so they are stacked on top of it. Hence all disks are on the final peg and the puzzle is solved. Move 216 10 = 11011000. The largest disk bit is 1, so disk 8 is on the final peg (2). Note that it sits on base number 11 ...

  6. Norm (mathematics) - Wikipedia

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

    In mathematics, a norm is a function from a real or complex vector space to the non-negative real numbers that behaves in certain ways like the distance from the origin: it commutes with scaling, obeys a form of the triangle inequality, and zero is only at the origin.

    en.wikipedia.org/wiki/Zero-sum_game

    Zero-sum game is a mathematical representation in game theory and economic theory of a situation that involves two competing entities, where the result is an advantage for one side and an equivalent loss for the other. [1]

  9. Euclidean distance - Wikipedia

    en.wikipedia.org/wiki/Euclidean_distance

    The Euclidean distance is the prototypical example of the distance in a metric space, [10] and obeys all the defining properties of a metric space: [11] It is symmetric, meaning that for all points and , (,) = (,). That is (unlike road distance with one-way streets) the distance between two points does not depend on which of the two points is ...
