# 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 LaTeX options `fleqn` and `leqno`, or
may inherit the options 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.
