# [Calc v4.2.4.2] How apply an operation to all selected cells? [closed]

I recieved a sheet with some numeric data.

I'd like to multiply all cells by given factor. By multiply I mean, I want to edit/change all selected cells values to **initial value x multiply factor**.

There are thousand cells in the sheet, so editing it manually would cost me many hours of work.

Example data:

```
Row | A | B | C
----|------|------|-----
1 | 100 | 5 | 20
2 | 1.20 | 1 | 5.95
```

I'd like to select A1:C2 and multiply all values by **x 1.2** (120% of initial value). Expected result would be:

```
Row | A | B | C
----|------|------|-----
1 | 120 | 6 | 24
2 | 1.44 | 1.20 | 7.14
```

Is this possible? How?
