I have a formula in cell A1 as =A2+A3, now i need the same formula in cell B1 as well however i dont want to copy paste the formula, i just want to give reference of A1 in B1 and B1 should calculate B2+B3 rather than A2+A3, the reason i want to do this if I change the formula in A1 it should take effect in B1 as well. Not sure if this is possible. Similarly, if the formula contains reference to any of the cells above below the formula cell the reference in B1 should dynamically change?

@Franco, actually I dont want to drag the formula, If I do that B1 will take the formula from A1 and change to B2+B3. In this case suppose I change the formula in A1 to =IF(A4="yes",B2+B3), this won't get applied to B1 unless I again drag the new formula. What I need is to change in one place and wherever there is a reference to this formula it should auto change with dynamic cell reference. So basically, I want to give reference to a formula wherever I want to use it and then create a repository of formulas to maintain, so any change I just do in the repository and the change takes effect wherever I give reference?
