Problem Statement
John just got a new job at a tech company. His manager asked him to calculate his monthly take-home salary after deducting taxes and insurance.
The calculation is simple: Take-home salary = Gross salary - (Tax amount + Insurance amount)
John needs to write a program that takes his gross salary, tax amount, and insurance amount as inputs and calculates his take-home salary.
This is a real-life scenario where basic arithmetic operations are used to solve financial calculations.
