Math Interpreter parses and evaluates mathematical expressions with the help of Visitor pattern.
As Wikipedia tells:
The visitor design pattern is a way of separating an algorithm from an object structure on which it operates. A practical result of this separation is the ability to add new operations to existent object structures without modifying the structures. It is one way to follow the open/closed principle.
It also serializes AST (Abstract Syntax Tree) in JSON object.
Supported operators: +, -, *, /, unary +, unary -, <, <=, >, >=, ==, &, |, ^ and ()
