    public static void main (String args[]) {

                int     intAnswer, a = 1, b = 2, c = 3;

                double  doubleAnswer, x = 4, y = 5, z = 6;

 

                        intAnswer = a + b % b /c * 2 * a / c;

                        System.out.println("1) " +intAnswer);

// 1) _________   

         

                        intAnswer = (a + (b % b)) /((c * 2 * a) / c);

// 2) _________    

        

                        intAnswer = ((a + b) % b /c) * (2 * (a / c));

                        System.out.println("3) " +intAnswer);

// 3) _________    

        

                        intAnswer = (int)y % b + (int)(x / z * b);
