python - invalid syntax on If Statment

I am trying to make a random number game but I have hit a wall. I do not understand why I am getting a Invalid syntax error on line 11. Any help would be great.

import random
ops = ['+', '-', '*', '/']
x = 0
score = 0
while x <= 10:
    num1 = random.randint(1,10)
    num2 = random.randint(1,10)
    operation = random.choice(ops)
    maths = int(eval(str(num1) + operation + str(num2)))
    answer = int(input("What is the answer to  that arithmetic question?")
    if answer == maths:
        print ("Correct, You scored a point")
        score = score + 1
    else:
        print ("No points scored, Incorrect Answer")
    print(num1,operation,num2, "=", maths)
    x = x + 1

Cheers.
