A mathematical mean is the average of a group of numbers. To find it, you add all of the numbers you're being asked to find the mean for and then divide by the number of numbers you added. In other words, the average.

There are other means which are useful in other circumstances. The two common ones are the geometric mean and the harmonic mean.
The geometric mean, for a group of n positive numbers is the nth root of the product of the numbers.
So, G(4,6,9) = cuberoot(4*6*9) =cuberoot(216) = 6
The geometric mean is useful with numbers that are used as multipliers, such as growth rates.
The harmonic mean of n numbers x1, x2, x3 ,... xn is the number H such that
n/H = 1/x1 + 1/x2 + 1/x3 + ... + 1/xn
The harmonic mean is useful when the average of rates is desired. For example, if you travel k miles at x mph and another k miles at y mph, your average speed would be H(x,y).
Mean is another name for 'average'. Here you add up the scores and divide this new number by how many scores there are.
in notation this is (Sigma (xf-xi)) / x
Meadian means middle.

An IQ score of 50 would indicate Mild or Moderate Retardation
those words either mean math or science words
Just ask a math teacher Im sure they'll know
what does key mean in math
The word (difference) in the question is indicating that you need to subtract. In a math operation, when you see the words difference, how much more, or exceed these all mean you need to subtract.
a
'About' means 'Approximately.'. pi is about 3.14 pi is approximately 3.14 pi is NOT equal to 3.14 pi is an irrational numbers which means that the decimals go to infinity. So any value given for 'pi' is only an approximation/about. pi ~ 3.14 pi~ 3.1416 pi ~ 3.141592 pi = 3.141592....

I do not know of such a word related to math(s)
There is no such math word, so it does not mean anything. You may wish to check your spelling before posting questions!
The word at means the least
the word by means 'times' or 'multiply'
it mean per rate
arithemetic mean
its mean like well its a math term its like distrubed fractions
