2. Absolute value - Wikipedia

   en.wikipedia.org/wiki/Absolute_value

   The absolute value of a number may be thought of as its distance from zero. In mathematics, the absolute value or modulus of a real number , denoted , is the non-negative value of without regard to its sign. Namely, if is a positive number, and if is negative (in which case negating makes positive), and . For example, the absolute value of 3 is ...

3. Addition - Wikipedia

   en.wikipedia.org/wiki/Addition

   Addition (usually signified by the plus symbol +) is one of the four basic operations of arithmetic, the other three being subtraction, multiplication and division. [2] The addition of two whole numbers results in the total amount or sum of those values combined. The example in the adjacent image shows two columns of three apples and two apples ...

4. Archimedean property - Wikipedia

   en.wikipedia.org/wiki/Archimedean_property

   In abstract algebra and analysis, the Archimedean property, named after the ancient Greek mathematician Archimedes of Syracuse, is a property held by some algebraic structures, such as ordered or normed groups, and fields. The property, as typically construed, states that given two positive numbers and , there is an integer such that .

   Glossary of mathematical symbols. A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various ...

6. Stretch factor - Wikipedia

   en.wikipedia.org/wiki/Stretch_factor

   The stretch factor of the pair is the ratio between these two distances, d(f(x),f(y))/d(x,y). The stretch factor of the whole mapping is the supremum of the stretch factors of all pairs of points. The stretch factor has also been called the distortion[disputed – discuss] or dilation of the mapping. The stretch factor is important in the ...

7. Order of operations - Wikipedia

   en.wikipedia.org/wiki/Order_of_operations

   In mathematics and computer programming, the order of operations is a collection of rules that reflect conventions about which operations to perform first in order to evaluate a given mathematical expression. These rules are formalized with a ranking of the operations. The rank of an operation is called its precedence, and an operation with a ...

   The standard absolute value on the integers. The standard absolute value on the complex numbers.; The p-adic absolute value on the rational numbers.; If R is the field of rational functions over a field F and () is a fixed irreducible polynomial over F, then the following defines an absolute value on R: for () in R define | | to be , where () = () and ((), ()) = = ((), ()).

9. Abscissa and ordinate - Wikipedia

   en.wikipedia.org/wiki/Abscissa_and_ordinate

   In mathematics, the abscissa (/ æbˈsɪs.ə /; plural abscissae or abscissas) and the ordinate are respectively the first and second coordinate of a point in a Cartesian coordinate system: -axis (vertical) coordinate. Usually these are the horizontal and vertical coordinates of a point in plane, the rectangular coordinate system.
