  • Your younger brother has a problem with a basic
    mathematic operations like addition, subtraction,
    multiplication, and division. Your parents ask
    you to develop one simple system using Visual
    Basic to help your brother.
  • Your system should have function button to
    calculate the additional, subtraction,
    multiplication, and division for at least two
    integer numbers
