Summary description: Typesetting reasoned calculations,  also called
calculational proofs.

Announcement text:
----------------------------------------------------------------------


    The "calculation" environment formats reasoned calculations, also
    called calculational proofs. The notion of reasoned calculations or
    calculational proofs was originally advocated by Wim Feijen and
    Edsger Dijkstra. The "calculation" package accepts options "fleqn"
    and "leqno" (with the same effect as LaTeX options "fleqn" and
    "leqno", and inherits these from the document class), it allows
    steps and expressions to be numbered (by LaTeX equation numbers,
    obeying the LaTeX "\label" command to refer to these numbers), and
    a step doesn't take vertical space if its hint is empty.  An
    expression in a calculation  can be given a comment; it is placed
    at the side opposite to the equation numbers.  Calculations are
    allowed inside hints although numbering and commenting is then
    disabled.
