Calculated column

[Anonymous]

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.

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"
