Front 1

Properties of Addition

Back 1

Associative, Cummutative, identity, inverse

Front 2

associative property

Back 2

The order that numbers are grouped in addition does not matter.
3+(4+5)=(3+4)+5

Front 3

commutative property

Back 3

The order that numbers are added does not matter. 4+5=5+4

Front 4

identity property

Back 4

The sum of any number and 0 is the original number. 5+0=5

Front 5

inverse property

Back 5

any number plus its opposite is 0.
5+(-5)=0
-4+4=0

Front 6

Properties of multiplication

Back 6

associative, cummutative, identity, property of zero, inverse, distributive

Front 7

associative property of multiplication

Back 7

The order that numbers are grouped in multiplication does not matter.
2x(3x7)=(2x3)x7

Front 8

cummutative property of multiplication

Back 8

The order that numbers are multiplied does not matter.
5x6=6x5

Front 9

identity property of multiplication

Back 9

any number times 1 is the original number. 14x1=14

Front 10

Property of zero (multiplication)

Back 10

Any number times 0 is 0. 23x0=0

Front 11

adding terms with variables

Back 11

only terms that have the same variable with the same exponent can be added or subtracted together. 3x cannot be added to 2y

Front 12

multiplying variables with exponents

Back 12

1st multiply the coefficients, then add the exponents of the variables.
(3x²)(-2x³)=-6x⁶

Front 13

acute triangle

Back 13

all angles less then 90 degrees

Front 14

right triangle

Back 14

has an angle equal to 90 degrees

Front 15

obtuse triangle

Back 15

has an angle greater than 90 degrees

Front 16

isosceles triangle

Back 16

has two sides of equal length

Front 17

equilateral triangle

Back 17

all three sides are equal in length

Front 18

congruent

Back 18

two polygons (not just triangles) that are exactly the same size

Front 19

similar

Back 19

two polygons (not just triangles) that are the same shape, but different size (proportionally)

Front 20

pythagorean theorem

Back 20

in any right triangle the square of the hypotenuse is equal to the square of the 2 legs added together.
a²+b²=c²

Front 21

area of a rectangle

Back 21

length x width

Front 22

area of a triangle

Back 22

1/2 base x height (expressed in unit squared)

Front 23

volume of rectangular prism

Back 23

length x width x height (expressed in units cubed)

Front 24

volume of a cylinder

Back 24

2πr²
r=radius

Front 25

area of a circle

Back 25

πr²

Front 26

mean

Back 26

average number

Front 27

mode

Back 27

number that occurs most often (if there is not a number that occurs more than once, there is no mode; if can be two modes if more than one number occurs the same) number of times

Front 28

median

Back 28

the middle number (if there are two numbers in the middle, it is the average of these two numbers)

Front 29

range

Back 29

the largest number minus the smallest number

Front 30

whole numbers

Back 30

positive numbers that do not have any decimals or fractions (1,2,3,4,5,6....)

Front 31

Integers

Back 31

numbers, positive or negative, and do not have a fraction or decimal (...-3, -2, -1, 0, 1, 2, 3...)

Front 32
