Reference Previous Cell

[TTEMAN]

Hi Everyone, whatever cell i use for a formula how do i tell it to look at the cell before it.
example, =sum(b1-a1)this is OK
but i want to replace 'a1' with
'the cell before the one i am putting in the formula'
you know it is a1 so do i but i dont want to reference it that way, just tell it to look at the previous cell. can this be done please, regards john

That's the point of Absolute and Relative references. For example, if you put in A2

=A1

and in B2

=$B$1

and drag them down, you should see in A3

=A2

and in B3

=$B$1

So, if you need a formula to look at the formula above it and you're "standing" in C3459, then just use

=C3458

and drag it down !

actually, that is exactly what you are doing already. B1-A1 is saying take cell B1 and subtract the cell before it in the same row.
