Least Common Multiple
(LCM) 
the smallest number that all numbers can become  uses the cake method (never smaller than the biggest number)


Greatest Common Factor
(GCF) 
the biggest number that all of the numbers can be divided by  uses the tree method (never bigger than the smallest number)


factor

a number that divides another number without a remainder (always equal to or smaller than the original number)
ie. factors of 24 = 1, 2, 3, 4, 6, 8, 12, 24 

multiple

the product of the original number and another number (always equal to or larger than the original number)
ie. multiples of 5 = 5, 10, 15, 20, 25 

ascending order

from smallest to biggest


descending order

from biggest to smallest


absoute value

the distance the number is from zero on a number line  the distance can NEVER be negative


composite number

a whole number that has factors besides 1 and itself  the smallest composite number is 4


prime number

a whole number whose only factors are 1 and itself  2 is the smallest prime and the ONLY even prime


coordinate pairs

used in graphing  (x,y)  the first number tells you right or left; the second number tells you up or down


divisibility rule for 2

if the number ends in 0, 2, 4, 6, or 8


divisibility rule for 5

if the number ends in 0 or 5


divisibility rule for 6

if it is divisible by BOTH 2 and 3


divisibility rule for 10

if it ends in 0


divisibility rule for 3

if the sum of the digits adds up to a number divisibile by 3
ie. 123 = 1 + 2 + 3 = 6; 6 is divisibile by 3 so 123 is divisible by 3 

divisbility rule for 9

if the sum of the digits is divisible by 9
ie. 63 = 6 + 3 = 9; 9 is divisible by 9 so 63 is divisible by 9 

equivalent

equal


equivalent fractions

two or more fractions that are equal to each other


equivalent decimals

two or more decimals that are equal to each other


exponent

shows repeated multiplication


factor tree

used for prime factorization; used to find a numbre's prime factors


frequency table

a 3 column chart that lists the items, a tally section, and the frequency


improper fraction

when the numerator (top number) is bigger than the denominator (bottom number)


numerator

the top number in a fraction


denominator

the bottom number in a fraction


integers

a set of whole numbers and their opposites
NOTE: 0 is not an integer 

inverse operations

opposite operations; they undo each other
addition  subtraction multiplication  division 

Least Common Denominator
(LCD) 
smallest common denominator a set of fractions can become


line plot

uses a number line and x's to represent data


mean

the average of the data  add up all of the data and divide by the number of items in the data


median

the middle number of a set of data in numerical order


mode

the most common number(s) of the set of data


range

the difference betwen the biggest and the smallest numbers in a set of data; subtract big minus small


order of operations

1. Parenthesis
2. Exponents 3. Multiply and Divide from LEFT to RIGHT 4. Add and Subtract from LEFT to RIGHT 

origin

(0,0)  where you start from when graphing ordered pairs


power

a number expressed using an exponent


prime factorization

uses factor trees to write the number as a product of its primes
ie. 24 = 2 x 2 x 2 x 3 

probability

the number of correct chances over the total number of chances


scientific notation

a number written as a prduct of two factors when the first is a number greater than 1 but less than 10 and the second is a power of 10


slope

rise over run; up or down over the left or right


square root

a number which when multiplied by itself equals the given number


symmetry

when one side of a figure is the mirror image of the other side


terminating decimal

a decimal that stops


repeating decimal

a number that repeats itself in a pattern


variable

a symbol, usually a letter, that stands for a number; an unknown


x  axis

the horizontal bar of a graph


y  axis

the vertical bar of a graph
