# MODE=MOST common

# MEAN=TOTAL of items ÷NUMBER of items
#RANGE=DIFFERENC between HIGHEST and LOWEST
# ASCENDING= always rearange data in order

# when multiplying you add the powers
# when dividing you subtract the powers
# when raising one power to another you multiply the powers
# fractions=apply the power to both the top and bottom
# to find a negative power =turn it upside down
# whatever is inside the brackets multiply 


# squared=by itself
# squared root is the reverse process
# squared root=what numer×by itself gives
# all numbers also have a negative square root- its the minus version of the normal one 

# cubed means multiplied by itself and then by itself again
# cube root= 3^ is the reverse process 3 cube root means what number 
#when a number is cubed it implies that it is multiplied itself by 3 times (example 3 cubes is 27)

# the front number must always be between 1 and 10.
# the power of 10 ,n, is how far the decimal point moves.
# N is positive for big numbers,n is is negative for small numbers. 

# and rule=the probability of event  A and B happening =a multiplied by B.
# or rule = the probability of either event A or B happening is equalto A+B.
# expected frequency of a result=probability×numbers of trials.

# data can be descriptive using words.
# data can measure quantities using numbers. 
# descreted data=uses exact numbers.
# contiuous data=can have any value.

# to×or÷=in standard form,rearange to put front numbers and powers of 10  together ,then multiply /divide both.
# for × or -, +/- =the front numbers only (but check the powers of 10 are the same). 

# a circle=360°
#1/2 circle= 180°
#1/4 circle=90°
#fraction of the total=angle÷360°
#find multiplyre to=an angle add totals 360÷total that multiply each number by the answer n

# line of best fit=correlation
# no line of best fit=no correlation

# acute angle= below 90° 
# obtuse angle = above 90°
# right angle = 90°
# reflex angle=^
# angles in a triangle = 180°
# anglles in a quadrilateral =360°
# angles on a straight line =180°
# allied angles= 180°

# exterior angles = 360°
# interior angle=180°- exterior angle.
# regular polygons 
   exterior angle 360°/n = number of sides.
# sum of the interior angles=(n-2)×180°
