If you mean Excel, you always need a formula; there is no way around that. As a shortcut to adding numbers individually, you can use the SUM() function. Within the parentheses, you can write a range, for example:
=SUM(A1:A4)
This is a function but it is still also a formula. You may have confused the two things. All functions in use are in formulas and you can have formulas that have no functions.
Because if the numbers change then you have to change the formula. Numbers commonly change in spreadsheets. You should put the numbers into cells and then refer to the cell in the formula. If the number in the cell changes, then the formula will be able to work without having to be changed, as it will use whatever value is in the cell.
