Well, it is a convention that _ is automatically assigned the last result and on Sage command line you can do sage: 1 + 2 3 sage: _ + 5 8 My point was that there are two separate computations here, but when entered in a single cell these two lines make "one computation", so _ does not get any value (also 3 is not displayed since only the last result is shown). -- You received this message because you are subscribed to the Google Groups "sage-cell" group.
