TermDefinition
Zero Property Anything multiplied by zero
Distributive Property Multiplying a sum (or difference) by a number is the same as multiplying each number (or difference) by the number and adding (or subtracting) the products.
Identity Property the properties that state that the sum of any number and zero is that number and the product of any number and 1 is that number.
Associative Property of addition Addends can be regrouped and the sum remains the same 1+(3+5)=(1+3)+5
Commutative Property Addition the order of addends can be changed and the sum remains the same. 3+7=7+3
Associative Property of Multiplacation factors can be regrouped and the product remains the same. 2*(4*10)=(2*4)*10
Commutative Property of Multiplacation the order of factors can be changed and the product remains the same. 3*5=5*3
Prime Number a number with the factors one and itself
Composite Number a whole number greater than one with more than two factors
Acute angle an angle more than zero but less than 90
Obtuse Angle an angle whose measure is between 180 and 90
strait angle an angle measuring 180
acute triangle a triangle whose angles are acute
equilateral triangle a triangle whose sides all have the same length
isosceles triangle a triangle with two sides that are the same length
obtuse triangle a triangle in which one angle is an obtuse angle
right triangle a triangle in which one angle is a right angle
scalene triangle a triangle in which no sides have the same length
Congruent Figures Figures that have the same size and shape
cube a solid figure with six flat surfaces called faces.all the faces are squares
face a flat surface of a polyhedron.
edge a line segment where two faces meet in a solid figure
average the # found by adding all the data and dividing by the # of data. also called the mean.
area The number of square units needed to cover a surface of figure
bar graph a graph that uses bars to show and compare data.
capacity The volume of a container measured in liquid units
celcius a unit of measure for measuring temperature in the metric system.
circle A closed plane figure made up of all the points that are the same distance from a given point
circle graph a graph in the shape of a circle that shows how all (100%) of set data has been divided into parts
circumference The distance around a circle
common denominators a # that is the denominator of two or more #'s.
common factor A number that is a factor of two or more given numbers
common multiple a # that is a multiple of two or more #'s.
cone A solid figure with one circular base; the points on the circle are joined to one point outside the base
congruent figures figures that have the same size and shape.
cubed A name for a number to the third power
cup a customary unit of capacity. 1 cup equals 8 fluid oz.
data Collected information
decimal a # with 1 or more places to the right of a decimal point
difference The number that results from subtracting 1 # from another
degree a unit of measure for angles and temperature
denominator the # below the fraction bar in a fraction
digits the symbols used to show numbers:0,1,2,3,4,5,6,7,8,9
divedend the number to be divided
divisor the number used to divide another number
edge a line segment where two faces meet in a solid figure.
elapsed time the difference between two times
equally likely having the same chance of occurring.
equal ratios ratios that can be represented by equivalent fractions.
equation a # sentence that uses an equal sign to show that two expressions have the same value.9+3=12
pi the ratio of the circumference of a circle to its diameter.Pi is approximately 3.14 or 22/7
estimate to give an approximate value rather than an exact answer.
evaluate to find the value of an expression.
expanded form a way to write a number that shows the place value of each digit.
exponent a number that tells how many times the base is used as a factor.
