Integer

one of the positive or negative

numbers 1, 2, 3, etc., or zero.

Compare whole number.

Rational Number

• a number that can be expressed exactly by a ratio of two integers.

Scientific Notation

a method for expressing a given quantity as a number having significant digits necessary for a specified degree of accuracy, multiplied by 10 to the appropriate power, as 1385.62 written as 1.386 × 103.

Perfect Square

• A number whose square root is an integer.

• For example, 4 is a perfect square because its square root is the integer 2.

Irrational Number

• A number that cannot be expressed as a fraction.

• Examples include some square roots such as 21/2 and 31/2, and numbers such as symbol π (the ratio of the circumference of a circle to its diameter).

Real Numbers

All the numbers that includes all rational and irrational numbers.

Density Property

• The property that states that there always exists another rational number between any two given rational numbers. This means that the set of rational numbers is dense.

Adjacent Angles

Two angles that share the same vertex and have one side in common between them.

Coefficient

• Mathematics . a number or quantity placed (generally) before and multiplying another quantity, as 3  in the expression 3x.

Distance Formula

• 1. distance(between two points) The length of the shortest path from

one point to another.

• distance formula (of two points) The distance between two

points (x1, y1) and (x2, y2) in the Cartesian coordinate

system can be given by: [(x1 - x2)2 + (y1 - y2)2]1/2

Domain

• The set of all possible input values for a function or relation.

Hypotenuse

• The side opposite the right angle in a right triangle.

Legs of a right Triangle

• Either of the sides in a right triangle opposite an acute angle. The legs are the two shorter sides of the triangle.

Range

• The difference between the maximum and minimum values in a set of data.

Slope

• Another name for gradient.

Prism

• A space figure with two parallel polygonal bases that are the same shape and the same size.

Scatterplot

• Data that is plotted as points on a graph to show a possible relationship between two sets of data.

Slope intercept form

• y = mx + bThis is called the

slope-intercept form because "m" is the slope and "b" gives the y-intercept. (For a review of how this equation is used for graphing, look at slope and graphing.)
