the number of times a base is used as a factor of repeated multiplication
exponent

side opposite to the right angle in a right triangle
hypotenuse

a real number whose deicmal form is nonterminating and nonrepeateing that cannot be written as the ratio of two integers
irrational number

a number that can be written as the ratio of two integers with a nonzero denominator
rational

either of the two shorter sides of a right triangle; the two legs form the right angle of the triangle
leg

a theorem that relates the lengths of the sides of a right triangle. The sum of the squares of the lengths of a right triangle equals the square of the length of the hypotenuse
Pythagorean theorem

one of two equal factors of a nonnegative number
square root

the distance a number is from zero on the number line. Example: 4=4 and 3=3
absolute value

two numbers that when added together equal 0. Example: 3.2+(3.2)=0
additive inverse

a mathematical sentence that contains an equals sign
equation

A mathematical phrase involving at least one variable. Expressions can contain numbers and operation symbols.
algebraic expression

a mathematical sentence that contains the symbols >, <, >, or <.
inequality

Pairs of operations that undo each other; Examples: Addition and subraction and multiplication and division.
inverse operation

monomials that have the same variable raised to the same power. In other words, only coefficients of terms can be different. Example: 3x^{3 }and 18x^{3 }
like terms

an equation that can be written in the form ax+b=c where a, b, and c are real numbers and a is not equal to 0.
linear equation in one variable

two numbers that when multiplied together equal 1. Example: 4 and 1/4
multiplicative inverse

the ________ of a nonvertical line is the ratio of the rise (vertical change) to the run (horizontal change) between any two point on the line
slope

two or more equations that together define a relationship between variables
system of equations

the collection of all items not in a set
complement of a set

a member or item in a set
element

a rule of matching elements of two sets of numbers in which an input value from the first set has only one output value in the second set
function

the set of all elements contained in all of the given sets
intersection of sets

a subset that does not contain every element of the parent set
null set

a rule that gives an output number for every valid input number
relation

a collection of numbers, geometric figures letters, or other objects that have some characteristic in common
set

a collection of items drawn entirely from a single set. This can consist of any number of items from a set ranging from none at all (a null ______) all the way up to the entire set (every set is a ______ of itself)
subset

the set of all elements that belong to at least one of the given two or more sets
union of sets

the __________ uses multiplication to find the number of ways two or more events can occur. (Two or more events that happen in succession)
counting principle

The outcomes for a specified event
favorable outcomes

The occurrence of one event does not affect the probability of the occurrence of the other event.
independent events

The possible results of an experiment
outcomes

the probability that an event occurs is a measure of the likelihood that the event will occur
probability

all possible outcomes of a given experiment
sample space

a treeshaped diagram that illustrates sequentially the possible outcomes of a given event
tree diagram
