Let's say I want to SUM, entire Row 2 (from A2, to E2), and the result of that SUM to appear on F2, on that same row.
Same with Row 3 and Row 4; I want the results of the SUM from Row 3, to appear in Row 3 (at F3 to be specific).
The same with Row 4; (I want the results of the SUM from Row 4, to appear in Row 4 [at F4 to be specific].
Important: (Because is school work and the list may increase) so if I want to apply this very exact same function (of SUM and adding result on same row; how can I apply this function automatically to... 100 rows, for example?
