What does the word average indicate in maths?

Answer 1

Average is the same as mean, which is a quantity having a value intermediate between the values of other quantities. To get a mean, you add all of the numbers together then divide the total by the number of numbers there were. I'll give an example:

9;2;7;0;17;84;3;4

You add the numbers together: 9+2+7+0+17+84+3+4=126

l l l l l l l l

there were 8 numbers: 1 2 3 4 5 6 7 8

divide the total by the number of numbers there were, so divide 126 by 8:

126/8=15.75

So, the mean, or average, of 9;2;7;0;17;84;3;4 is 15.75

I hope that helped!

P.S. your grades are made by using average: 100%+92%+99%=291%

291%/3=97%
