    Default Random Number Generator

    I have to generate two random numbers, add them, and let the user type in the answer, and display if they are correct and if not give them the correct answer. I can't figure out how to know what the correct answer is, any hints?
    This is what I have so far . . . .

    a =(int) Math.random()*9 +1;
b= (int) Math.random()*9 +1;
problem = a + b;
System.out.println(a);
System.out.println("+", b);

    From that snippet of code, it appears that problem is the correct answer (ie it is a and b added together).
