How to creating recurring maths questions

What function do i use to generate 10 questions? I've already generated one question, however it just stops after it's answered. Its part of a maths quiz. And also how to add score each time answer is correct?

import random
ops = ['+', '-']

num1 = random.randint(0,9)

num2 = random.randint(0,9)

operation = random.choice(ops)

print(num1, operation, num2, '= ?')

answer = (input) ("What is your answer?")

maths = eval(str(num1) + operation + str(num2))

if answer ==(repr(maths)):
 print("correct")

else:
     print("Incorrect! The correct answer is",(maths))
