There is no single answer to the question. Numbers in dreams refer to something in that specific dreamer's life, such as an address, significant date or a fragment of a phone number. Generally they have disappointingly mundane meanings.

It doesn't really mean anything it came to John in a dream.
The American Experience - 1988 Big Dream Small Screen 9-6 was released on: USA: 10 February 1997
Sum = 42 Count = 6 Mean = Sum/Count = 42/6 = 7
Dream On - 1990 Significant Author 6-4 was released on: USA: 9 August 1995
If you mean 6 2/9, then it's (6 * 9 + 2) / 9 or 56 / 9
Numbers do not have specific universal meanings in dreams. In other words, the number 9 in your dream could refer to an anniversary or address or the date of an appointment, while in another person's dream, the same number would mean something entirely different.
(5 + 6 + 6 + 9) = 26/4 = 6.5. The mean of the four numbers is therefore 6.5.
The mean is the average = (6+9+101+4)/4 = 30
'Mean' is the average of a range. (6+9+7+3+10+9)÷6=7.333333333 (7.33 to two decimal points).
GM(6, 9) = sqrt(6*9) = sqrt(54) = 7.3485 approx.
do you mean what is 3+6+9-12? The answer is 6: 3+6=9 9+9=18 18-12=6 :)
