Well, isn't that just a happy little question! When we talk about the sum of a number "n" and 12, we're simply saying to add those two values together. It's like bringing two friends together for a little party on your canvas - they join forces to create something new and beautiful. So, just add n and 12 together, and see what lovely result you get!
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.
2 (N + 3)
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)
0.3333
There are three numbers. Their sum is 12-n + 12 + 12+n = 36 So their mean is 36/3 = 12.

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.)
where n = number of sides total sum of interior angles: (n - 2) * 180 so (12-2)*180 then divide that number by n 10*180 / 12
