It means that you can choose any number for n (since it is a variable) and then the sum (the answer when you add two numbers together) can be found.
Algebraically it looks like n+12 = ? (if n were 7 the answer would be 19).
12 + n
The sum of a number and its negative (additive inverse) is zero. For any nonzero value n, n + (-n) = 0
There are three numbers. Their sum is 12-n + 12 + 12+n = 36 So their mean is 36/3 = 12.
Mean absolute deviation = sum[|x-mean(x)|]/n Where mean(x) = sum(x)/n and n is the number of observations. |y| denotes the absolute value of y.
To find the missing number in a data set with a mean of 15, you need to know the total number of values (n) in the data set and the sum of the existing numbers. The mean is calculated as the sum of all values divided by n. If you have the sum of the existing numbers, you can rearrange the formula: missing number = (mean × n) - sum of existing numbers. Without additional information, the exact missing number cannot be determined.
12 + n
Where n = any number, n(12+3)
The sum of a number and its negative (additive inverse) is zero. For any nonzero value n, n + (-n) = 0

4/(n + 12)
There are three numbers. Their sum is 12-n + 12 + 12+n = 36 So their mean is 36/3 = 12.
Mean absolute deviation = sum[|x-mean(x)|]/n Where mean(x) = sum(x)/n and n is the number of observations. |y| denotes the absolute value of y.

12 more than a number means: __+12 (a number plus 12). You can express this as an algebraic expression: n+12 or 12+n(n representing a number.)
