Integers

numbers preceded by either a positive or negative sign


1/4 = .25

divide 1.00/4=.25


convert decimal to percent

shift decimal point 2 places to the right..ex..
0.135 = 13.5% 

decimal to percent

shift decimal point 2 places to left
98% = .98 

inverse operations

addition=subtraction
multiplication= division they undo each other 

factors

any of the numbers or symbols in mathematics that, when multiplied together, form a product


Prime number

number with 2 wholenumber factors1 and the number itself ex.
2,3,5,7,11,13,17 

two positives or two negatives =

positive


mixing a positive and a negative

negative


perimeter

measure of the distance around a figure


area

measure of the interior of a figure


perimeter of a rectangle

P=2l+2w
l=length w=width 

perimeter of a square

P=4s s=side
s=5ft so perimeter P=4(5ft.)=20ft. 

perimeter of a triangle

P=s1+s2+s3


area of a rectangle

A=lxw


area of a square

A=S2 s=5ft.
A=(5ft)2=25 sq. ft. 

area of triangle

A=1/2bh b=base, h=height
b=3in., h=4in. a=1/2(3in.x4in.)=1/2(12in.)=6in. 

radius of circle

distance from the center of the circle to the edge


diameter of circle

line segment that passes through the center of circle, or twice the measure of the radius


pi=

3.14


circumference of a circle

C=pi x d or,
C=2xpixr d=diameter r=radius 

area of circle

A=pi x r2 ex. r=5cm
A=3.14x25cm=78.5cm 

circle

360*


halfcircle

180*


Complementary angles

sum of 2 angles = 90*


Supplementary angles

Sum of 2 angles = 180*


right angle

angle measuring 90*


acute angle

angle measuring less that 90*


obtuse

angle measuring more that 90*


triangle angles

sum of the measures of the three angles of any triangle = 180*


Pythagorean theorem

a2 + b2 = c2
