Times (*, ×)

x*y*z, x×y×z or x y z
represents a product of terms.
  • The character × is entered as Esc * Esc or \[Times]. It is not the same as \[Cross].
  • The default value for arguments of Times, as used in x_. patterns, is 1.
  • Times[] is taken to be 1.
  • 0x evaluates to 0, but 0.0x is left unchanged.
  • Unlike other functions, Times applies built-in rules before user-defined ones. As a result, it is not possible to make definitions such as 2*2=5.
