Prime Number

A prime number is an integer p greater than 1 with exactly two positive factors: 1 and p.

Composite Number

Coordinate(s)

A number assigned to each point on the number line which shows its position or location on the line. In a coordinate plane the ordered pair, (x,y), assigned to each point of the plane, shows the point’s position in relation to the x-axis and y-axis.

Coordinate Plane

A plane that consists of a horizontal and vertical number line, intersecting at right angles at their origins. The number lines, called axes, divide the plane into four quadrants. The quadrants are numbered I, II, III, and IV beginning in the upper right quadrant and moving counterclockwise.

Quadrant

In this quadrant, your coordinate point is - -

positive and positive

Quadrant I

negative and negative

Quadrant III

In this quadrant, your coordinate point is -

positive and negative

Quadrant IV

Counting Numbers

Denominator

The denominator of a fraction indicates into how many equal parts the whole is divided. The denominator appears beneath the fraction bar.

Dividend

The quantity that is to be divided.

Divisor

Equivalent

A term used to describe fractions or ratios that are equal.

Exponents

Also called powers. It is a symbol written above and to the right of a number or mathematical expression to indicate the operation of raising to a power.

Factor

An integer that divides evenly into a dividend. Use interchangeably with divisor except in the Division Algorithm.

Improper Fraction

A fraction in which the numerator is greater than or equal to the denominator.

Integers

The collection of integers is composed of the counting numbers, the negatives, and zero; ... −4, −3, −2, −1, 0, 1, 2, 3, 4...

Numerator

The expression written above the fraction bar in a common fraction to indicate the number of parts counted.

Ordered Pair

A pair of numbers that represent the coordinates of a point in the coordinate plane with the first number measured along the horizontal scale and the second along the vertical scale.

Origin

The point with coordinate 0 on a number line; the point with coordinates (0,0) in the coordinate plane.
