Factors are numbers you can multiply together to get another number: Example: 2 and 3 are factors of 6, because 2 × 3 = 6. 3 and 4 are factors of 12, because 3 × 4 = 12. Also 2 × 6 = 12 so 2 and 6 are also factors of 12.

Prime factor

A factor that is a prime number: one of the prime numbers that, when multiplied, give the original number. Example: The prime factors of 15 are 3 and 5 (3×5=15, and 3 and 5 are prime numbers).

Square root

Finding the square root of a number is the inverse operation of squaring that number. Remember, the square of a number is that number times itself. The perfect squares are the squares of the whole numbers.

Powers of numbers

The number represented here as x is called the base, and n is called the power or exponent. The basic definition of a number written in exponential notation states that the base should be multiplied by itself the number of times indicated by the expo

Index notation

Index notation is a short way of writing a number being multiplied by itself several times. For example, instead of writing: 4 x 4 x 4. It is easier to write

Integer

An integer (from the Latin integer meaning "whole") [note 1] is a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 5½, and √2 are not.

volume

Volume is the amount of space inside of something like a cube. Volume is always measured using linear measurements (like inches and centimeters) cubed to represent three dimensions. Example: For the cube on the right, the volume is 75 cubic inches. T

congruent shapes

Two polygons are congruent if they are the same size and shape - that is, if their corresponding angles and sides are equal. Move your mouse cursor over the parts of each figure on the left to see the corresponding parts of the congruent figure on th

Mean

In mathematics, mean has several different definitions depending on the context. In probability and statistics, mean and expected value are used synonymously to refer to one measure of the central tendency either of a probability distribution or of t
