The formulas in the worksheet, unless manual calculation is in operation.
There is no simple answer to that. Each worksheet is different. It depends on what it is that needs to be done, so they will have different formulas every time. A person who knows how to use Excel and knows what needs to be calculated, will be able to create the formulas. There are different ways of doing the same thing, so it is possible to use different variations of formulas that will achieve the same result. So, as you can see, there is no straightforward answer. It is down to the knowledge and experience of the person creating the worksheet as to what formulas they will use.
Formulas will adjust when rows and columns are added or deleted.
