Addition and subtraction -

Our 6 year old son is working on addition and subtraction.

public class Main {
    public static void main(String[] args) {
        Math.Math();

    }
}

import java.util.Random;

public class Math {
    public static void Math() {
        //Division with Divisor as number
        System.out.println();
        System.out.println();
        Random rand = new Random();
        int high;
        int low;
        for (int x = 1; x < 11; x++) {
            for (int y = 1; y < 3; y++) {
                int rand_x = rand.nextInt(19) + 1;
                int rand_y = rand.nextInt(19) + 1;
                if (rand_x >= rand_y) {
                    high = rand_x;
                    low = rand_y;
                } else {
                    high = rand_y;
                    low = rand_x;
                }


                System.out.printf("___" + " " + " + " + " " + low + " = " + high + "       ");

                rand_x = rand.nextInt(19) + 1;
                rand_y = rand.nextInt(19) + 1;
                if (rand_x >= rand_y) {
                    high = rand_x;
                    low = rand_y;
                } else {
                    high = rand_y;
                    low = rand_x;
                }

                System.out.printf(high + " - " + " ___ " + " = " + low + "       ");
            }
            System.out.println();
            System.out.println();
        }
    }

}
