My new program skips everything inside it? Help

import java.util.; import java.io.;

public class m {

public static void main(String[] args) {
  Scanner reader = new Scanner(System.in);
  Random rand = new Random();
  Console console = System.console();

  String again = new String("Yes");

  while(again.equalsIgnoreCase("Yes")){
    String morg = console.readLine("Graphing or Multiplication?(G or M):  ");
    while(morg.equalsIgnoreCase("M")){
      int multi = rand.nextInt(12);
      int multi2 = rand.nextInt(12);
      int ans = multi * multi2;
      System.out.println(multi + "*" + multi2);
      int an = reader.nextInt();
      if(an == ans){
        again = console.readLine("Correct!\n\nWould you like to try again?(Yes or No)\n");
      }
      if(an != ans){
        console.printf("Incorrect! Try again...\n");
        }

      if(again.equalsIgnoreCase("No")){
          System.out.println("Exiting...");
          System.exit(0);  
        }
     }
     while(morg.equalsIgnoreCase("G")){
       int multi = rand.nextInt(12);
       int multi2 = rand.nextInt(12);
       int multi3 = rand.nextInt(20) - 40;
       if(multi2 > multi3 || multi2 > multi){
        break;
       }
       int ans = multi / multi2;
       int ans2 = multi3 / multi2;
       System.out.println(multi + "x + " + multi2 + "y =" + multi3);
       System.out.println("Enter X:  ");
       int an = reader.nextInt();
       System.out.println("Enter the second number:  ");
       int an2 = reader.nextInt();
       if(an == ans && an2 == ans2){
         again = console.readLine("Correct!\n\nWould you like to try again?(Yes or No)\n");
       }
       if(an != ans){
         console.printf("Incorrect! Try again...\n");
         }
         if(again.equalsIgnoreCase("No")){

           System.exit(0);  
         }
        }
     again = console.readLine("Would you like to go again?:  ");
       }
      }
     }

This should do it for you.

import java.io.Console; import java.util.Random; import java.util.Scanner;

public class Main {

public static void main(String[] args) {
    Scanner reader = new Scanner(System.in);
    Random rand = new Random();

    String again = new String("Yes");

    while(again.equalsIgnoreCase("Yes")){
        System.out.println("Graphing or Multiplication?(G or M):  ");
        String morg = reader.nextLine();
        while(morg.equalsIgnoreCase("M")){
            int multi = rand.nextInt(12);
            int multi2 = rand.nextInt(12);
            int ans = multi * multi2;
            System.out.println(multi + "*" + multi2);
            int an = reader.nextInt();
            if(an == ans){
                System.out.println("Correct!\n\nWould you like to try again?(Yes or No)\n");
                again = reader.nextLine();
            }
            if(an != ans){
                System.out.printf("\"Incorrect! Try again...\\n\"");
            }

            if(again.equalsIgnoreCase("No")){
                System.out.println("Exiting...");
                System.exit(0);
            }
        }
        while(morg.equalsIgnoreCase("G")){
            int multi = rand.nextInt(12);
            int multi2 = rand.nextInt(12);
            int multi3 = rand.nextInt(20) - 40;
            if(multi2 > multi3 || multi2 > multi){
                break;
            }
            int ans = multi / multi2;
            int ans2 = multi3 / multi2;
            System.out.println(multi + "x + " + multi2 + "y =" + multi3);
            System.out.println("Enter X:  ");
            int an = reader.nextInt();
            System.out.println("Enter the second number:  ");
            int an2 = reader.nextInt();
            if(an == ans && an2 == ans2){
                System.out.println("Correct!\n\nWould you like to try again?(Yes or No)\n");
                again = reader.nextLine();
            }
            if(an != ans){
                System.out.println("Incorrect! Try again...\n");
            }
            if(again.equalsIgnoreCase("No")){
                System.out.println("Exiting...");
                System.exit(0);
            }
        }
        System.out.println("\"Would you like to go again?:  \"");
        again = reader.nextLine();
    }
}

}
