algebra
the branch of mathematics that deals with relationships between numbers, utilizing letters and other symbols to represent specific sets of numbers, or to describe a pattern of relationships between numbers
binomial expression
an algebraic expression with two unlike terms
capacity
the greatest volume that a container can hold
circumference
the distance around a circle
coefficient
a number multiplied by a variable
constant term
a quantity that does not change; a term that has no variable
expression
a mathematical phrase involving at least one variable and sometimes numbers and operation symbols - not an equation or inequality
factor
the numbers that are multiplied together to create the product - the term 2b has 2 factors (2 and b, because they are multiplied together)
function notation
uses the symbol f(x) to replace y in the equation
integer
the set of numbers ...,-3, -2, -1, 0, 1, 2, 3, and so forth; whole numbers and their opposites
irrational number
a number that cannot be written as the ratio or quotient of two integers. Irrational numbers in decimal form are non-terminating and non-repeating.
monomial expression
an algebraic expression with one term
perimeter
the sum of the side lengths of a polygon
Polynomial expression
a monomial or the sum or difference of two or more monomials where the coefficients are real numbers
Pythagorean Theorem
in any right triangle, the sum of the squares of the lengths of the legs is equal to the square of the hypotenuse: a^2 + b^2 = c^2
Radical expression
an expression made up of a radical symbol and a radicand
radicand
the number underneath the root symbol; in √a, the a is the radicand
rational number
a real number that can be written as a ratio or quotient of two integers. Rational numbers in decimal form are terminating or repeating.
real numbers
the set of rational and irrational numbers
standard form of a polynomial
the form of a polynomial that places the terms in descending exponent order
term
a number, a variable, or the product or quotient of numbers and variables
trinomial expression
an algebraic expression with three unlike terms
variable
a letter or symbol used to represent a number
volume
the amount of space occupied by an object
whole numbers
the numbers 0, 1, 2, 3, and so forth; the non-negative integers
