Variable
a quantity which during a calculation is assumed to vary or be capable of varying in value. Example:4x: x is the variable
Constant
a quantity or parameter that does not change its value whatever the value of the variables, under a given set of conditions.
Coefficient
a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x y).
Base
a number used as the basis of a numeration scale.
a number in terms of which other numbers are expressed as logarithms.
Exponent
a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression (e.g. 3 in 23 = 2 × 2 × 2).
Independent variable
independent variable; plural noun: independent variables
a variable (often denoted by x ) whose variation does not depend on that of another.
dependent variable
dependent variable; plural noun: dependent variables
a variable (often denoted by y ) whose value depends on that of another.
Domain
the set of possible values of the independent variable or variables of a function.
Range
the set of values that a given function can take as its argument varies.
Interval
real numbers that contains all real numbers lying between any two numbers of the set. For example, the set of numbers x satisfying 0 ≤ x ≤ 1 is an interval which contains 0, 1, and all numbers in between
Interval notation
a shorthand method for writing sets of numbers, namely continuous ranges of real numbers
Roster notation
Roster notation of a set is a simple mathematical representation of the set in mathematical form
Set builder notation
the different symbols used in the process of working within and across the sets. The simplest set notation used to represent the elements of a set is the curly brackets { }. An example of a set is A = {a, b, c, d}.
Conjunction
A conjunction is a statement formed by adding two statements with the connector AND. The symbol for conjunction is ‘∧’ which can be read as ‘and’.
Disjunction
The other important form of connective logic is disjunction. A disjunction is a statement involving an or. For two statements p and q, it is written in mathematical notation as p∨q p ∨ q . Again, both p and q have to be either true or false statements.
Union
the set that comprises all the elements (and no others) contained in any of two or more given sets.
the operation of forming a union.
System
A system of a linear equation comprises two or more equations and one seeks a common solution to the equations. In a system of linear equations, each equation corresponds with a straight line corresponds and one seeks out the point where the two lines intersect.
NXn
We can define the set of integers as the set NxN where “x” is the Cartesian Product. In set theory, the Cartesian Product is the combination of all the elements of one set with all the elements of the other set forming pair. So, if N = { 1, 2, 3 … }, then NxN = { (1,1), (1,2), (1,3), …, (2,1),(2,2), …, }
Root of an equation
(Alg.) that value which, substituted for the unknown quantity in an equation, satisfies the equation.
Intercept
MATHEMATICS
the point at which a given line cuts a coordinate axis; the value of the coordinate at that point.
Coordinator
A pair of numbers that describe the position of a point on a coordinate plane by using the horizontal and vertical distances from the two reference axes. Usually represented by (x,y) the x-value and y-value.
Coordinate versus value
A set of values that show an exact position. On graphs it is usually a pair of numbers: the first number shows the distance along, and the second number shows the distance up or down. Example: the point (12,5) is 12 units along, and 5 units up.
Inequality
the relation between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
MATHEMATICS
a symbolic expression of the fact that two quantities are not equal.
Inequality notation
In math, an inequality shows the relationship between two values in an algebraic expression that are not equal. Inequality signs can indicate that one variable of the two sides of the inequality is greater than, greater than or equal to, less than, or less than or equal to another value
