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.
