arguments. :)
Yes they can be. There are text functions in Excel which can manipulate text, which is what labels are. Some of those functions can get numeric values, like the LEN function getting the length of a piece of text. That number could then be used in a calculation. So although it is not often done, there are times when labels can be used in calculations.
no null values will not be included explanation when oracle parse the query the null values will be omitted for some reason if you want to consider null values you have to use some oracle functions like nvl or nvl2

Logical functions like IF functions or others can be used.

There are some facilities built into Excel such as validation, evaluation and auditing, which can help in testing formulas. What you really should do is work with values where you know what the outcome should be and see do your formulas give the correct results. More complicated formulas can be more difficult to test and find errors in and it isn't always clear what is causing the problem. As computers are based on the laws of mathematics, there are lots of things that determine how calculations work that users don't understand fully. See the related question below.
SUM is a function. It can be used as part of a formula which can carry out a calculation.
a formula is an equation that performs mathematical calculations on number values in cells
Average
Yes they do. Spreadsheets are very good at doing What-If calculations. There are lots of functions available, like the IF function, to help. Other facilities can also be used, so spreadsheets are ideal for it. They are used extensively for doing what-if calculations.
In programming: They let you do generic calculations, with numbers that you don't know in advance. In algebra: They let you do calculations with unknown values - either generic calculations, or do calculations to find such unknown values in a specific case.
