Custom Math Class that can check if a number is even or odd, calculate your rental payment, mean, percent, and percentage of a number. My custom class for some math problems, including a function to calculate payment on a house or rental agreement.
This class is used to calculate various different types math problems that are not covered in the regular math class.
