# Write a program that uses random numbers to quiz a user

import random

def main():
  # generate two random numbers
  a = random.randint (1, 100)
  b = random.randint (1, 100)
  sum = a + b

  # prompt the user to add those numbers
  response = eval (input (str(a) +  ' + ' + str(b) + ' = ' ))

  # check if he is correct
  if (sum == response):
    print ('correct')
