A flat surface of a three-dimensional figure.

One of two or more expressions that are multiplied together to get a product.

A diagram representing a systematic way of determining all the prime factors of a number.

To break a number into its factors.

Temperature scale in which water boils at 212

A sequence whereby each number is the sum of the two numbers preceding it.

Two dimensional shapes are often referred to as figures.

Not infinite. Finite has an end.

A reflection of a two dimensional shape, a mirror image of a shape.

Imaginary point used in parabolas, hyperbolas, and ellipses.
