Calculated column

Hey guys, 
I wanna calculate a new column with the following formula "column A - column B + column C" but the problem is that I can only get the value right for the first row. 
how can I write a DAX function that would get the value of last index " e.g. in excel I would write ="NewColumn"2+[@C] and so on"
thanks !

@Anonymous I don't understand what you are trying to do, are you trying to take the value of C from the previous row? If so, that is likely not going to work as that essentially requires recursion.

@Greg_Deckler  

well yeah that's basically what I'm trying to do, so recursion functions are not possible in power BI? 
e.g. @C2 the value should be "1790930,93-1631244,46 + 2540804,2" 

@Anonymous Not really. Previous Value aka "Recursion" - Microsoft Power BI Community
