VBA for repeating a calculation and pasting a value-only list of inputs/outputs

So I have a single input cell (say D1) and a single output cell (say D2). I would like to make a table of pasted values for a range of inputs/outputs in the range A1:B100.
I'm guessing this would be something using a For...Next loop (For i = 1 to 100) but I'm totally new to VBA and don't know how to write the macro.
Any help would be very much appreciated. I hope I've explained the problem well enough!
