        System.out.println ("MathsQuiz" + " " + answer);

Answer 1

The problem is that you are referencing a variable that you have not declared on this line:

System.out.println ("MathsQuiz" + " " + answer);

I presume you want to reference the variable you declared in the add() method. The simplest way to go around this is to call the method directly instead of referencing the variable. Like this:

  public static final void main(String[] str){
        MathsQuiz mq = new MathsQuiz();
        System.out.println ("MathsQuiz: sum of 1,2,3,4,5" + ":" + mq.add(1,2,3,4,5);
   }
