absolute value

Back 1

the distance that a number is from zero on a number line

Front 2

complement of a set

Back 2

the set of all elements in the universal set that are not in a given set

Front 3

compound inequality

Back 3

two inequalities that are joined by "and" or "or"

Front 4

disjoint sets

Back 4

sets that do not have any elements in common

Front 5

empty set

Back 5

a set that does not contain any elements

Front 6

equation

Back 6

a mathematical sentence that uses an equal sign

Front 7

equivalent inequalities

inequalities that have the same set of solutions

Front 8

inequality

Back 8

a mathematical sentence that compares the values of two expressions using an inequality symbol

Front 9

intersection

a notation for listing all of the elements in a set using set braces and commas

Front 13

set-builder notation

Back 13

a notation used to describe the elements of a set

Front 14

union

Back 14

the set that contains all of the elements of two or more sets

Front 15

universal set

Back 15

the set of all possible elements from which subsets are formed
