So till now I want to make a simple button but it gives me an error screen, what am I doing wrong? Here's my code:

```
import tkinter as tk
import math
import time

tk = tk.Tk()
tk.geometry()
tk.attributes("-fullscreen", True)

exit_button = tk.Button(tk, text = "Exit", height = 2, width = 2, command = tk.destroy)
exit_button.place(x=1506, y=0)

tk.mainloop()

```
