positive.code: ----
  where the arithmetic addition is an operand to the arithmetic multiplication and, hence, results in `20` (rather than `11`).
  
  === Left-to-right precedence
  
  Most precedence level include multiple operators.

  == Proposal
  
  The precedence in openCypher is defined by (1) _precedence levels_ and (2) _intr level precedence_.
  Both are defined in the following two subsections.
