a sequence in which each term after the first is found by adding a constant, the common difference D, to the previous term.
least common multiple
smallest number that is the multiple of two or more other numbers

act of determining the unknown values in an equation
extraneous solution
solution of a simplified version of an equation that does not satisfy the original equation
Properties of an equality
Transformations used to isolate the variable in an equation.
step function
a function whose graph is a series of line segments.
Slope Form
m= y minus y divided by x minus x
multiplicative identity property
for any number a, a x 1 = 1 x a
a quantity possessing only magnitude.
What is X in this equation?
having a common boundary; bordering; contiguous.
a rectangular array of numbers, algebraic symbols, or mathematical functions, esp. when such arrays are added and multiplied according to certain rules.
a number or quantity placed (generally) before and multiplying another quantity, as 3 in the expression 3x.
the branch of mathematics that deals with general statements of relations, utilizing letters and other symbols to represent specific sets of numbers, values, vectors, etc., in the description of such relations.
a sequence of terms combined by addition, as 1 + ½ + ¼ + ⅛ + … ½ n.
linear equation
a first-order equation involving two variables: its graph is a straight line in the Cartesian coordinate system.
cramer's rule
a method involving the determinant of the coefficients, for calculating a unique solution for a given system of linear equations.

(in a right triangle) the ratio of the hypotenuse to the side adjacent to a given angle.
periodic function
a function of a real or complex variable that is periodic.
(in a right triangle) the ratio of the side adjacent to a given angle to the side opposite.
a plane curve such that the sums of the distances of each point in its periphery from two fixed points, the foci, are equal. It is a conic section formed by the intersection of a right circular cone by a plane that cuts the axis and the surface of the con
