Algebraic expression
The number that is raised to a power
Base
The number by which a variable is multiplied. Ex: the 2 in 2x
Coefficient
This is formed when two number lines intersect at their zero points.
Coordinate plane
A(b+c) = ab+ ac
Distributive property
The number that tells how many factors there are of the base
Exponent
The inequality symbol >
Greater than
