repeating a formula throughout a worksheet

[jtnru]

Hi
I havent used excell for some years and have set up a basic worksheet, but
am wanting to repeat a formula each third row which is row 1 balance plus row
2 minus row 3 equals balance as displayed in row 4 and then repeat this
thoughtou the worksheet for several columns ( if that makes sense- im sure it
can be done not sure how thou and have looked through help topics everywhere
so if any one can help in basic language it would be great thanks.

Click & Hold left mouse button to select the WHOLE area you want to repeat
then release mouse button and hover over the bottom right corner of selected
until cursor turns to black cross rather than white then click & hold right
mouse button and drag to desired point.

All formula and data will be copied over, you can then delete just the data
