In this code, I do not see any difference between cell.value and cells.formula when it comes to entering a formula.

They both did the same thing. Am I right? Is there any case, I have to use cells.formula instead of cells.value? Thank you very much.

Code:

```
Sub insert_formula()
Cells(11, 1).Value = "=sum(a1:a10)"
Cells(12, 1).Formula = "=sum(a1:a10)"
End Sub
```
