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!

Well, darling, when you add a number "n" to 12, you're just performing a simple addition operation. So, in mathematical terms, the sum of a number "n" and 12 is simply n + 12. It's like putting 12 extra cherries on top of your number "n" sundae.
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).
The sum of a number n and 12 means adding the value of n to 12. In mathematical terms, it can be represented as n + 12. This operation results in a new value that is the combined total of n and 12.
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.
