After entering the values in the range A1:C2, and the formulas in the range D1:E2, with the cursor in D1, hold the shift key down and highlight the range D1:E2. Do a Copy (I use Ctrl+c), go to A1, click on Edit, Paste Special, Values, OK. Yes, you don't want D1:E2 to show a new, recaclulated value. My only suggestion is to just don't take them into account. But, if they bother you, why not place the formulas in the range G1:H2, so they will be further away, or in a similar range beyond the normally visible part of the sheet, so they wll be out of sight?
I could suggest deleting D1:E2 after pasting in A1:B2, but, I assume you wish to use the formulas over and over, so, this would not be an option.
Please let us know if this helps you out, or if you requiere more help.
