how to buildup up the operaters mathmatics multiply and division?

[desighner]

class Parent{
protected int x=100;
protected int y=200;
public void add(){
int z=x+y;
System.out.println("The addition is"+z); }
}
class Child2 extends Parent{
private int a= 10;private int b= 20;
private void write (){
int c= a+ b;
System.out.println("The addition is"+ c);}
public static void main(String[] arg){
Child2 c=new Child2();
c.add();
c.write();
c.x=1000;
c.y=2000;
System.out.println("Now x is" + c.x);
System.out.println("Now y is" + c.y);
}
}
class Brother2 extends Parent{
public static void main(String[] arg){
Brother2 c=new Brother2();
c.add();
c.x=7000;
c.y=5700;
System.out.println("Now x is" + c.x);
System.out.println("Now y is" + c.y);
}
}
please if any gentlemen and ladies here can type sentences as explanation how does the total amout appears according to which step is reqired for compiler to work?
in other words if(now x is" + c%x);
if(now y is" + c %y);
thank you

are you asking how to multiply without using the multiplication symbol? Well, that's just recursive addition. And division is subtraction.
