    This is a program that can calculate many real world
    things for you, such as Compound Interest and Monthly Payments; it can
    even help you make a Budget Sheet!

    Compound Interest: Interest that is calculated on the combined total
    of the original sum borrowed principal and the interest it has already accrued.

    Monthly Credit Card Disbursement: How many months it will take to pay off a credit
    card balance with a specific APR and Monthly Payment.

    Monthly Payment: How much you will have to pay per month on an amount of money
    with a specific interest rate over a specific amount of time.

    Sales Tax: Shows how much an item is after the standard Indiana sales tax.

    Double Time: Shows how long it will take to double your initial value in years.

    Budget Sheet: This shows you your spending based off your monthly income and includes
    Categories such as Home, Food, Car and so on, with subcategories such as Home: Insurance,
    Rent or Car: Gas, Insurance. You can decide what to put in, it does not have to be Home Or Food,
    it can be things such as personal. It then will ask how much you spend on those per month, and
    then have a total per category and a grand total to show you how much you can spend or if you have
    to cut some expenses.
    Example Questions:
    How much is your monthly income? 2000
    What is a monthly expense?(Enter one at a time) Home
    What is a monthly expense?(Enter one at a time) Personal
    What is a monthly expense?(Enter one at a time) Next
    What specifically is/are the expense(s) for Home (Enter one at a time) Rent
    What specifically is/are the expense(s) for Home (Enter one at a time) Insurance
    What specifically is/are the expense(s) for Personal (Enter one at a time) Netflix
    How much do you spend on Rent a month? 500
    How much do you spend on Insurance a month? 135
    How much do you spend on Netlfix a month? 15

    Written Check Example: This shows you a diagram of a check and how to fill it out.

    Have fun calculating, See ya on the other side!
