Use labview program show me the step,,

Question 1: esign a VI which performs the functionality of calculator with ollowing specifications, Calculator should take two inputs,with names a and b and perform following four functionalities, and answer should be displayed in output c 1 . Add = (2a+b) 2. Subtract = (a-2b) 3. Multiply = (4a"(-b)) 4. Divide = (57a) . Use "case structure" and "Enum to implement above mentioned four cases in single VI If user selects 'Add' operator then first function should be executed and so on. Whole VI should be controlled by a stop button.
