Class 3- BRF Buliding Plus

Expression types define the computational power of BRFplus. Each expression type defines a self-contained computational unit with a well-defined logic. Expressions use a context or nest other expressions to calculate, determine, or derive a result. An expression can be considered to be an instance of an expression type behaving according to the expression type's logic. An expression can be reused as a nested building block for a rule, starting with a function as its assigned top expression. BRFplus comes with a set of common expression types and is regularly enhanced by new expression types. You can create your own expression types and use it in rules.
