If you mean: 8 9 10 11 and 12 then the average mean is 10
'Mean' is the average of a range. (6+9+7+3+10+9)÷6=7.333333333 (7.33 to two decimal points).
Mean = (9 + 10 + 2 + 5 + 5)/5 = 31/5 = 6.2
Mean: 13.6 Median: 15 Mode: 16, 18, 15, 9, 10
The mean (or average) of 8, 9, and 10 is 9.

It's a short way of saying "out of." 9 of 10 = 9 out of 10 = 9 divided by 10 = 9/10
12+5+9+10=36/4=9 9 is the Mean of 12, 5, 9, and 10 To find the mean of something, add all the figures and then divide by the number of figures.
If you mean: -9-10+8 then their sum is -11
I'm not quite sure if this is what you mean but: 9/9=1 9+1=10 9/9=1 10*1=10 The whole thing: (9/9)*(9+(9/9))=10
If you mean: 8 9 10 11 and 12 then the average mean is 10

'Mean' is the average of a range. (6+9+7+3+10+9)÷6=7.333333333 (7.33 to two decimal points).
MEAN = ( 8+10 )/2 = 18/2 =9
If you mean 90 - 9/10, then the answer's 89 1/10. If you mean 90 - nine-tenths of 90 [90 - 9/10(90)], then the answer's 9.
