add the numbers

[dzug]

You won't get a sensible answer to this coz there isn't one. What numbers? Those expressed in figures or those expressed as words or both? Include the results of the equations or not? The roman numbers or not? If so do the x's in 5x5x0 count as roman numbers or not?

Is 15 fifteen, or 1 and 5, or both?

And so on ad nauseam.
