How would I choose between several different formulas in a cell based on a
variable in another cell?


Simplified Example:

Let's say I have three fields, field 'A' has a number, field 'B' is our
variable and field 'C' either adds/subtracts or multiplies field 'A' by 5.

How do we get the formula in 'C' to change based on the value in 'B'? Let's
assume for the moment there are more than 7 different formulas so an IF/Then
might be tricky.

Is there anyway to do this without a macro?
