| Term | Definition |
| Monomial | Polynomial with one term |
| Binomial | Polynomial with two terms |
| Trinomial | Polynomial with three terms |
| Expression | a mathematical statement that includes numbers,
operations, and variables to represent a number or
quantity |
| Term | a number, a variable, or the product of a number and
variable(s) |
| Polynomial | a monomial or a sum of monomials |
| Factor | one of two or more numbers or expressions that are
multiplied to produce a product |
| Variable | a letter used to represent a value or unknown quantity
that can change or vary |
| Like terms | terms that contain the same variables raised to the same
power |
| Constant terms | a term whose value does not change |
| Constant | a quantity that does not change |
| base | the factor being multiplied together in an exponential
expression; in the expression ab
, a is the base |
| Closure | a system is closed, or shows closure, under an operation if
the result of the operation is within the system |
| coefficient | the number multiplied by a variable in an algebraic
expression |
| exponent | the number of times a factor is being multiplied together
in an exponential expression; in the expression a
b
, b is the
exponen |
| quadratic expression | an algebraic expression that can be written in the form
ax2 + bx + c, where x is the variable, a, b, and c are
real numbers, and a ≠ 0 |
| order of operation | the order in which expressions are evaluated from left
to right (grouping symbols, evaluating exponents,
completing multiplication and division, completing
addition and subtraction) |
