it is possible to declare a variable in excel lets say N=10, then if i type letter N in a cell and that cell makes part of a sum, that cell will be counted as 10?

You can name a cell by selecting it, clicking the field with its address (in upper-left corner) and entering name (in your example "N"). Value in this cell is value on your variable. Good idea is to make separate sheet that will contain variables (you'll avoid mess), but it's not necessary.
And then you can use it in formulas, f.e.: =A1*N. But remember, if you want just fill cell with its value, use =N instead of N.

If i do that the value 10 will be displayed in that cell where i put =N, i need that N will be displayed in the cell not its own value and only in the sum N to be replaced with 10

So I don't think you will be able to do that, as Excel has to distinguish letter N and variable N.
