without getting too into it, i need to access a private variable to use that number in a calculation. i have a function to return it, my question becomes if I call

1 2 3 4 5

int PVreturn() { return privateVariableName };

is this something that I can drop into a math equation?

example:

1 2 3 4 5 6

int PvMaths() { int newvariable newvariable = PVreturn() + 6 };

if not what's the best way I could do that?
