How to Convert Number into Signs (Math) in Python

I am trying to make Math Quiz that asking with two random numbers (1, 10) with randomly choice with sum, difference or product. I used z = random.randint(1, 3) to generate sum, difference or product, but I want to use this numbers converting to signs like "x", "/", or "+" to shown output to ask Question because I am new to Python language and I am trying to learn on how to convert numbers to symbols.

My Code Here:

import random

def askNum():
  while(1):
    try:
      userInput = int(input("Enter a number: "))
      break
    except ValueError:
      print("Incorrect Input!")

  return userInput

def askQuestion():
  x = random.randint(1, 10)
  y = random.randint(1, 10)
  z = random.randint(1, 3)

  print(" 1 = product \n 2 = sum \n 3 = difference")
  print("What is " + str(x)+" " + str(z)+" " + str(y)+"?")

  u = askNum()
  if z == 1 and u==x*y:
    return 1  #product
  elif z == 2 and u==x+y:
    return 1 #sum
  elif z == 3 and u==x/y:
    return 1 #difference
  else:
    return 0
amount = 10
correct = 0
for i in range(amount):
  correct += askQuestion()

print("You got %d correct out of %d" % (correct, amount))

Reality Output:

dm15125@isu:/u1/work/Python/math> python3 mathquiz.py
 1 = product
 2 = sum
 3 = difference
What is 4 2 6?
Enter a number: 10
 1 = product
 2 = sum
 3 = difference
What is 7 2 6?
Enter a number: 13
 1 = product
 2 = sum
 3 = difference
What is 3 2 3?
Enter a number: 6
 1 = product
 2 = sum
 3 = difference
What is 8 3 4?
Enter a number: 2
 1 = product
 2 = sum
 3 = difference
What is 8 3 10?
Enter a number: 0.8
Incorrect Input!
Enter a number: .8
Incorrect Input!
Enter a number: 0
 1 = product
 2 = sum
 3 = difference
What is 2 2 6?
Enter a number: 8
 1 = product
 2 = sum
 3 = difference
What is 6 3 4?
Enter a number: 1.5
Incorrect Input!
Enter a number: 2
 1 = product
 2 = sum
 3 = difference
What is 7 1 10?
Enter a number: 70
 1 = product
 2 = sum
 3 = difference
What is 9 2 5?
Enter a number: 14
 1 = product
 2 = sum
 3 = difference
What is 5 1 10?
Enter a number: 50
You got 8 correct out of 10

EXPECTED OUTPUT:

dm15125@isu:/u1/work/Python/math> python3 mathquiz.py
What is 4 + 6?
Enter a number: 10
What is 7 + 6?
Enter a number: 13
What is 3 + 3?
Enter a number: 6
What is 8 / 4?
Enter a number: 2
What is 8 / 10?
Enter a number: 0.8
Incorrect Input!
Enter a number: .8
Incorrect Input!
Enter a number: 0
What is 2 + 6?
Enter a number: 8
What is 6 / 4?
Enter a number: 1.5
Incorrect Input!
Enter a number: 2
What is 7 * 10?
Enter a number: 70
What is 9 + 5?
Enter a number: 14
What is 5 * 10?
Enter a number: 50
You got 8 correct out of 10
