INTEGER

1. A member of the set of positive whole numbers {1, 2, 3, . . . }, negative whole numbers {-1, -2, -3, . . . }, and zero {0}.

2. A complete unit or entity.

RATIONAL NUMBERS

A number capable of being expressed as an integer or a quotient of integers, excluding zero as a denominator.

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 × 10 3  .

PERFECT SQUARE

a rational number that is equal to the square of another rational number.

2. a polynomial that is the square of another polynomial.

IRRATIONAL NUMBERS

a number that cannot be exactly expressed as a ratio of two integers

REAL NUMBERS

a rational number or the limit of a sequence of rational numbers, as opposed to a complex number.

DENSITY PROPERTY

States that,between two rational numbers on a number line…

Adjacent angles

two angles having the same vertex and having a common side between them.

Coefficient

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

2. Physics. a number that is constant for a given substance, body, or process under certain specified conditions, serving as a measure of one of its properties: coefficient of friction.

Distance Formula

The formula , which is used to find the distance between two points (x1, y1) and (x2, y2), is called the Distance Formula.

Distance Formula

Domain

Domain of a relation is the set of all x-coordinates of the ordered pairs of that relation. 

  Hypotenuse

the side of a right triangle opposite the right angle.

Legs of a right Triangle

In a right triangle, the sides opposite to the acute angles are called the Legs of a Triangle.

Rational Number

a number that can be expressed as an integer or the quotient of an integer divided by a nonzero integer

Range

Set of data is the difference between the largest and smallest.

Slope

The slope of a line is a number that measures its "steepness", usually denoted by the letter m. It is the change in y for a unit change in x along the line.

Scientific Notation

Where a number is written in two parts:

First: just the digits (with the decimal point placed after the first digit),

Followed by: ×10 to a power that would put the decimal point back where it should be.

Prism

A solid object that has two identical ends and all flat sides.

The cross section is the same all along its length.

The shape of the ends give the prism a name, such as "triangular prism"

Scatter plot

A graph of plotted points that show the relationship between two sets of data.

In this example, each dot represents one person's weight versus their height.

Slope intercept form

the equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept
