Maarten Fokkinga submitted the calculation package. Version number: 1.0 License type: lppl1.3 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.
This package is located at http://mirror.ctan.org/macros/latex/contrib/calculation More information is at http://www.ctan.org/pkg/calculation We are supported by the TeX Users Group http://www.tug.org . Please join a users group; see http://www.tug.org/usergroups.html .
Thanks for the upload. For the CTAN Team Manfred Lotz

calculation – Typesetting reasoned calculations, also called calculational proofs

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 package accepts options fleqn and leqno (with the same effect as the options fleqn and leqno, or may inherit the options from the document class). It allows steps and expressions to be numbered (by equation numbers, obeying the \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.
