How to automatically fill data automatically in other row once you put data in a row

[DeyKaushik]

My concern is like if I fill data in cell A1 what formula I can use to automatically fill the data that is required in cell B1 C1 D1

@DeyKaushik 

That all depends on what is required in cells B1, C1, D1, etc.

You need to be a bit more descriptive here. Are you adding, multiplying, something else?
