title: Python random math generator fail
body: <p>okay i have now encountered a problem with my code, when I run my code it will not give chance for the user to answer </p>
  
  <pre><code>print ("what is your username")
  name = input () .title()
  print (name, "welcome")
  import random
  score=0
  question=0
  for i in range(10):
  
   ops = ["+", "-", "*"]
  num1 = random.randint (0,10)
  num2 = random.randint (0,10)
  oparator = random.choice(ops)
  Q=(str(num1)+(oparator)+(str(num2)))
  print (Q)
  
  
  if oparator =='+':
      answer=num1+num2
      if Q == answer:
          print ("correct")
          score=score+1
      else:
           print ("incorrect")
  
  
  if oparator =='-':
      answer=num1-num2
      if Q == answer:
          print ("correct")
          score=score+1
      else:
           print ("incorrect")
  
  
  if oparator =='*':
      answer=num1*num2
      if Q == answer:
          print ("correct")
          score=score+1
      else:
  
          print ("incorrect")
  </code></pre>
  
  <p>i am unsure on how to fix this problem as i am new to programming.
  it will not let the user guess and will just print incorrect </p>
  
  <pre><code>what is your username
  kurt
  Kurt welcome
  2*0
  incorrect
  &gt;&gt;&gt; 
  </code></pre>
