// notice how this returns double, why? because the quotient is a result from division,
// and two numbers dividing could easily result in a fraction, and a fraction is essentially
// a decimal pointed number when converted to a number

  int product = firstNumber + secondNumber;
  double quotient = firstNumber / secondNumber;
  double resultingSum = product + quotient;
