Step 4:

Write the code as shown below.

import tkinter as tk

root= tk.Tk()

canvas = tk.Canvas(root, width = 300, height = 280)
canvas.pack()

entry1 = tk.Entry (root)
canvas.create_window(210, 100, window=entry1)

entry2 = tk.Entry (root)
canvas.create_window(210, 140, window=entry2)

entry3 = tk.Entry (root)
canvas.create_window(210, 240, window=entry3)

labelTitle = tk.Label(root, text='Simple Calculator')
labelTitle.config(font= ('Georgia', 14))
canvas.create_window(150, 40, window=labelTitle)

labelNum1 = tk.Label(root, text='Insert Number 1:')
labelNum1.config(font= ('helvetica', 10))
canvas.create_window(100, 100, window=labelNum1)

labelNum2 = tk.Label(root, text='Insert Number 2:')
labelNum2.config(font= ('helvetica', 10))
canvas.create_window(100, 140, window=labelNum2)

labelNum3 = tk.Label(root, text='Result:')
labelNum3.config(font= ('helvetica', 10))
canvas.create_window(100, 240, window=labelNum3)

def add ():
v1 = entry1.get ()
v2 = entry2.get ()

labelResultAdd = tk.Label(root, text= float(v1)+float(v2),font=('helvetica', 10, 'bold'),bg='white')
canvas.create_window(210, 240, window=labelResultAdd)

buttonAdd = tk.Button(text='+', command=add, bg='blue', fg='white', font=('helvetica', 9, 'bold'),
width = 5)
canvas.create_window(90, 190, window=buttonAdd
def sub ():
v1 = entry1.get ()
v2 = entry2.get ()
