entry2 = Entry(root, text=s, width=16, font='Arial 18')

entry2.place(x=20, y=140)

def b1_click():

  vidp = eval(entry1.get())

  entry2.delete(0, END)

  entry2.insert(0, vidp)

b1 = Button(root, text='Розв’язати', command=b1_click)

b1.place(x=40, y=90)

def b_click(operation):

  s = entry1.get() + operation + entry2.get()

  result = eval(s)

  entry3.delete(0, END)

  entry3.insert(0, result)

def b2_click():

  result = eval(s)

  entry3.delete(0, END)

  entry3.insert(0, result)

def b3_click():

  s = entry1.get() + "*" + entry2.get()

  result = eval(s)

  entry3.delete(0, END)

  entry3.insert(0, result)

def b4_click():

  s = entry1.get() + "/" + entry2.get()

  result = eval(s)

  entry3.delete(0, END)

  entry3.insert(0, result)

root.mainloop()

Answer 2

Ответ:

самое простое  

Объяснение:

a=int(input('Введите число 1: '))

b=int(input('Введите число 2: '))

print('a+b= ',a+b)

print('a-b= ',a-b)

print('a*b= ',a*b)

print('a/b= ',a/b)
