 # 12 Expressions
 
 ## 12.1 General
 
 An expression is a sequence of operators and operands. This clause defines the syntax, order of evaluation of operands and operators, and meaning of expressions.
 
 An expression *E* is said to ***directly contain*** a subexpression *E₁* if it is not subject to a user-defined conversion [§10.5](conversions.md#105-user-defined-conversions) whose parameter is not of a non-nullable value type, and one of the following conditions holds:
 
 - *E* is *E₁*.
 - If *E* is a parenthesized expression `(E₂)`, and *E₂* directly contains *E₁*.
 - If *E* is a null-forgiving operator expression `E₂!`, and *E₂* directly contains *E₁*.
 - If *E* is a cast expression `(T)E₂`, and the cast does not subject *E₂* to a non-lifted user-defined conversion whose parameter is not of a non-nullable value type, and *E₂* directly contains *E₁*.
