The sum of a single number is itself!
The sum is the answer when you have added. ex. 2+3, the sum is 5.
The sum of the individual digit is itself

The sum of any one number is just itself.
The sum of a single number is itself, so the answer is 406812.
If you add a single number - in this case minus seven - the "sum" is the number itself.
The sum is the total of numbers added together.

A shape does not have a sum. The angles of a shape have a sum, the lengths of its sides have a sum, the number of its diagonals are a sum, but the shape itself certainly does not have any sum!
You may think that there is a unique solution to that problem, but that is not the case. Any positive number can be added to the negative version of itself to obtain a sum of zero (-589 added to 589 is zero, etc.) The simplest case, of course, is to add zero to zero, getting a total of zero.
