 .Chains of binary operators
 ====
-In chains of binary operators, the operator have left-to-right associativity, i.e. for every two operators, the operator appearing earlier (more left) in the query string takes precedence and the operator tree is left-deep.

 .Associative binary operators
 ====
-Where the semantics of operator is associative (e.g. addition), a right-deep operator tree produces the same result as a left-deep operator tree.
