If you mean, you want to clock on A5 - where that formula is - and have the formula bar show the answer instead of the formula? why< you can see the answer in the A5...if you change what displays in the formula bar, the formula is gone (if you enter)
If you just want to temporarily see the answer, click on the celll, press F2 (edit), then F9 (calc). As I said though, if you now hit ENTER instead of ESCAPE, that formula is gone
