SAXON MATH 8 / 7

AVERAGE

# found when the sum of 2 or more #'s is divided by the # of addends in the sum; also called MEAN

COUNTING #'S

#'s used to count; the members of the set {1,2,3,...}, also called NATURAL NUMBERS.

DIVISOR

1) a # by which another # is divided 2) a factor of a number

COORDINATE(S)

1) a # used to locate a point on a # line 2) an ordered pair of #'s used to locate a point in a coordinate plane

FACTOR

1) noun: 1 of 2 or more #'s that are multiplied 2) noun: a whole # that divides another whole # without a remainder 3) verb: to write as a product of factors

DEGREE

1) unit for measuing angles 2) unit for measuring temperature

INDEPENDENT EVENTS

2 events are independent if the outcome of 1 event does not affect the probability that the other event will occur.

CONSTANT

a # whose value doesn't change

DECIMAL FRACTION

a decimal number. 3 1/2 is NOT a decimal fraction. 3.24 is

DIAGONAL

a line segment, other than a side, that connects 2 vertices of a polygon

GEOMETRY

a major branch of mathematics that deals with shapes, sizes, & other properties of figurews.

DOUBLE-LINE GRAPH

a method of displaying a set of data, often used to compare 2 performances over time

DIVIDEND

a number that is divided (the # under, not on the side of)

FRACTION

a number that names part of a whole

EQUATION

a statement that use symbol "="to show 2 quantities are =

CHANCE

a way of expressing the likelihood of an event; the probability of an event expressed as a percent.

EXPANDED NOTATION

a way of writing a # as the sum of the products of the digits and the place value of the digits

DIVISIBLE

able to be divided by a whole number without a remainder

FOUR FUNDAMENTAL OPERATIONS

addition, subtraction, multiplication & division

INEQUALITIES

algebraic statements that have a

EXPONENTIAL EXPRESSION

an expression that indivates that the base is to be used as a factor the # of times shown by the exponent

DISTRIBUTIVE PROPERTY multiplication is distributive over addition

any # times the sum of 2 addends is equal to the sum of that same # times each individual addend a x (b + c) = (8 x 2) = (8 x 3)

DIGIT

any of the symbols used to write #'s: 0,1,2,3,4,5,6,7,8,9

CUMMUTATIVE PROPERTY OF ADDITION a + b = b + a

changing the order of addends doesn't change their sum. unlike addition, subtraction is not commutative.

COMMUTATIVE PROPERTY OF MULTIPLICATION a x b = b x a

changing the order of factors doesn't change their product. unlike multiplication, division is not commutative.

COMPOSITE NUMBER

counting # greater than 1 that's divisible by a # other than itself and 1. every composite # has 3 or more factors.,

NATURAL NUMBERS

counting numbers, the numbers we use when we count

EQUIVALENT FRACTIONS

different fractions that name the same amount

DIAMETER

distance across a circle through its center

COMPLEX FRACTION

fraction that contains one or more fractions in its num & denom

IMPROPER FRACTION

fraction with a numerator equal to or greater than the denominator. all improper fractions are = or greater than 1

FACT FAMILY

group of 3 #s related by addition & subtraction or by multiplication & division. 4 fact statement can be formed using the #'s in a fact family

COMPOUND INTEREST

interest that pays on previously earned iterest

GREATEST COMMON FACTOR

largest whole # that is a factor of 2 or more indicated #'s

VARIABLES EVALUATE

letters used to represent numbers in formulas and expressions which are not constant. the process used with an expression by calculating its value when the vaiables are assigned specific numbers

HISTOGRAM

method of displaying a range of data; a special type of bar graph that displays data in intervals of equal size with no space between bars

ADDENDS SUM

numbers that are added the result of addition

FACTORS PRODUCT

numbers that are multiplied the result of multiplication

INVERSE OPERATIONS

operations that undo each other addition & subtraction multiplcation & division raising to powers & finding roots

IDENTITY PROPERTY OF MULTIPLICATION

product of any # & 1 is = to initial #. a x 1 = a. #1 is referred to as multiplicative identity.

CROSS PRODUCT

product of the numer of 1 fraction & the demon of another

FUNCTION

rule for using 1 # (an input) to calculate another # (an output). each input produces only 1 output.

DIRECTED NUMBERS

see signed numbers

IDENTITIY PROPERTY OF ADDITION

sum of any # & 0 is = to the initial #. A + 0 = 0. the #0 is referred to as the additive identity.

DECIMAL NUMBER

symbol in decimal # used as reference point for place value

COEFFICIENT

the # that multiplies the variable(s) in an algebraic term. if no # is specified, the coefficient is 1.

ABSOLUTE VALUE

the distance from the graph of a number to the number 0 on a number line. the symbol for absolute value is a vertical bar on each side of a numeral or variable

ASSOCIATIVE PROPERTY OF ADDITION

the grouping of addends doesn't affect their sum. unlike addition, subtraction is not associative.

ASSOCIATIVE PROPERTY OF MULTIPLICATION

the grouping of factos does not affect their product. unlike multiplication, division is not associative.

ADDITIVE IDENTITY

the number 0 because adding zero to any # doesn't change the #

DIFFERENCE

the result when the subtrahend is taken from the minuend

EXPONENT

the upper # in an exponential expression that shows how many times the base is to be used as a factor

ESTIMATE

to determine an approximate value

EVALUATE

to find the value of an expression

DEPENDENT EVENTS

two events are dependent if the outcome of one event affects the probility that the other event will occur

DIVISION QUOTIENT

when a dividend is divided by a divisor the result of division

WHOLE NUMBERS

when a zero is included with a set of counting numbers then it is a set of whole numbers
