 symbol which represents one or more numbers variable a number; a value which does not change constant mathematical phrase which includes numbers and operation symbols numeric expression mathematical phrase which includes numbers, variables, and operation symbols algebraic expression mathematical sentence which contains an equals sign equation an equation which contains one or more variables open sentence accepted order of operations PEMDAS replace a phrase with its simplest name simpligy tells how many times a number is used as a factor exponent has two parts, a base and an exponent power number in a power used as a factor base substitute given values for variables and simplify evaluatef mathematical sentence which compares the value of two expressions using an inequality symbol inequality any example which proves a statement false counterexample two numbers which are the same distance from zero on a number line opposites distance of a number from zero on the number line absolute value rectangular arrangement of numbers in columns and rows matrix an item in a matrix element multiplicative inverse reciprocal number by which you multiply all elements in a matrix scalar number, variable, or product of a number and variable in an algebraic expression term numerical factor of a term coefficient terms which have the same variable factors like terms two number lines that intersect at right angles coordinate plane point of intersection of two number lines origin horizontal axis x-axis vertical axis y-axis four sections made by the two axes in a coordinate plane quadrants x-coordinate abscissa y-coordinate ordinatef graph which relates two types of data scatter plot shows a correlation on a scatter plot more clearly trend line values of variables which make an equation true solution equations which have the same solution equivalent equations equation which is true for every value of the variable identityf integers which differ by 1 consecutive integers a constant rate uniform motion distance = rate * time rate or distance formula equation involving two or more variables literal equation values used to describe a set of data measure of central tendency sum of all data items divided by the number of data items mean middle value when the numbers in a data set are arranged in order median data item that occurs the most often mode difference between the greatest and smallest data values in a set range a data value which is much lower or higher than other values in the data set outlier display of data made by using the digits of the values stem and leaf plot any number that makes an inequality true solution inequalities with the same solution equivalent inequalities two inequalities joined by the word and ...or...or compound inequalities compound inequality which uses the word and conjunction compound inequality which uses the word or disjunction equation which states that two rations are equal proportion figures which have the same shape but not the same size similar figures an enlarged or reduced drawing that is similar to an actual object or place scale drawing ratio of a distance in a scale drawing to the corresponding actual distance scale amount of change divided by the original amount times 100 percent change one half of the measuring unit greatest possible error greatest possible error divided by the measurement times 100 percent error how likely an event is to occur probability result of a single trial outcome any outcome or group of outcomes event all of the possible outcomes sample space number of favorable outcomes divided by the number of possible outomes theoretical probability consists of all the outcomes not in the event complement of an event number of times an event occurs divided by the number of times the experiment is done experimental probability events that do not influence one another independent events events that influence each other dependent events a set of ordered pairs relation set of first coordinates in a relation domain set of second coordinates in a relation range a relation that assigns exactly one value in the range to each value in the domain function a way to determine if a relation is a function by analyzing the graph vertical line test equation which describes a function function rule using f(x) to describe function outputs function notation input values of a function independent variable output values of corresponding input values dependent variable a function in the form y = kx where k does not equal zero direct variation a function in the form xy=k where k does not equal zero inverse variation coefficient of x in a direct variation constant of variation making conclusions based on patterns you see inductive reasoning a conclusion reached by inductive reasoning conjecture a number patternf sequence each number in a sequence term a type of sequence which is formed by adding a fixed number to each previous term arithmetic sequence fixed term in an arithmetic sequence common difference
