    Trivial edit to start discussion.

    What’s happening at the start here? We have both tropical rig and semiring defined. The latter is given with the extension by {}\{\infty\}. Is this just duplication with a mistake?

    At semiring having given 4 definitions, it says

    The nLab uses the second definition to define a semiring, and the fourth definition to define a rig. The first and third are then called nonunital semirings and nonunital rigs respectively.

    Do we really have this as a policy?

    Of course not. But best to take this to the discussion in the thread on “semiring”.
