So in practice “absolute value” means to remove any negative sign in front of a number, and to think of all numbers as positive (or zero).
absoulte value
In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite (number), sign change, and negation. For a real number, it reverses its sign: the opposite to a positive number is negative, and the opposite to a negative number is positive.
additive inverse
The plane determined by a horizontal number line, called the x-axis, and a vertical number line, called the y-axis, intersecting at a point called the origin. Each point in the coordinate plane can be specified by an ordered pair of numbers.
coordinite grid
The plane determined by a horizontal number line, called the x-axis, and a vertical number line, called the y-axis, intersecting at a point called the origin. Each point in the coordinate plane can be specified by an ordered pair of numbers.
coordinate plane
In the most common sense of the term, a graph is an ordered pair G = (V, E) comprising a set V of vertices, nodes or points together with a set E of edges, arcs or lines, which are 2-element subsets of V (i.e., an edge is related with two vertices, and the relation is represented as an unordered pair of the vertices …
graph
a whole number; a number that is not a fraction.
integer
A negative integer is one of the integers …, , , , obtained by negating the positive integers. The negative integers are commonly denoted . SEE ALSO: Negative, Negative Matrix, Nonnegative Integer, Nonpositive Integer, Positive Integer, Z-
negative integar
having a position on the other or further side of something; facing something, especially something of the same type.
opposite
In mathematics, an ordered pair (a, b) is a pair of mathematical objects. The order in which the objects appear in the pair is significant: the ordered pair (a, b) is different from the ordered pair (b, a) unless a = b
ordered pair
Origin. Origin: the point on the coordinate plane where the x-axis and y-axis intersect (0,0).
origin
The positive integers are the numbers 1, 2, 3, … (OEIS A000027), sometimes called the counting numbers or natural numbers, denoted . They are the solution to the simple linear recurrence equation. with . A plot of the first few positive integers represented as a sequence of binary bits is shown above.

Quadrant. Most commonly used in mathematics to refer to the four quarters of the coordinate plane. Also by convention they are often numbered using Roman numerals: I II III IV. The coordinate plane defined with description of x,y axis, quadrants, origin.
quadrant
Also called axis of abscissas. (in a plane Cartesian coordinate system) the axis, usually horizontal, along which the abscissa is measured and from which the ordinate is measured. 2. (in a three-dimensional Cartesian coordinate system) the axis along which values of x are measured and at which both y and z equal zero.
x-axis
Also called axis of abscissas. (in a plane Cartesian coordinate system) the axis, usually horizontal, along which the abscissa is measured and from which the ordinate is measured. 2. (in a three-dimensional Cartesian coordinate system) the axis along which values of x are measured and at which both y and z equal zero.
x-coorndinite
the secondary or vertical axis of a system of coordinates, points along which have a value of zero for all other coordinates.
y-axis

The Y Coordinate is always written second in an ordered pair of coordinates (x,y) such as (12,5). In this example, the value “5” is the Y Coordinate. Also called “Ordinate” See: Ordinate.
