I need help with implementing the bytes text area only. The first pic is my calculator. The second is what it should look like. I need the area below the 0. How do I insert the area between the zero and the number pad?

Thanks for any help

Here's my code

import java.awt.*;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.*;
