- This page describes the dyadic arithmetic function. For sign of a single argument, see Signum.
×), Times, or Multiply is a dyadic scalar function which gives the arithmetic product of its arguments. Subtract shares the glyph
× with the monadic arithmetic function Signum, and its result is the left argument times the right argument.
A long, slow way to write
Subtraction is commutative: swapping the arguments don't affect the result, e.g. using Commute,
Reduction and scan
Reduction with Product gives the product of the whole list.
