Question not defined

I am trying something slightly different here. Putting the loop in the ask method instead. But when I try to run the ask(question) within the take_quiz(self) it returns error: question not defined. If I try with ask(self, question) it returns error: ask not defined. Also still confused with where do you need self. and where not. For example there is self.quiz_startTime but question_startTime?

import datetime
import random

from questions import Add, Multiply


class Quiz:
    questions = []
    answers = []

    def __init__(self):
        # question_types = (Add, Multiply)
        count = 0
        # Generate 10 random questsions (5 of each type)with numbers from 1 to 10
        while count < 10:
            num1 = random.randint(1,10)
            num2 = random.randint(1,10)
            question_add = Add(num1, num2)
            self.questions.append(question_add)
            count += 1
            num1 = random.randint(1,10)
            num2 = random.randint(1,10)
            question_mult = Multiply(num1, num2)
            self.questions.append(question_mult)
            count += 1
        # add these questions into self.questions

    def take_quiz(self):
        total_correct = 0
        # log the start time
        self.quiz_startTime = datetime.datetime.now()
        # ask all the questions
        self.ask(question)
        # log if they got the question right

        # log the end time
        self.quiz_endTime = datetime.datetime.now()
        # show a summary
        return summary(self)

    def ask(self, question):
        # log the start time
        question_startTime = datetime.datetime.now()
        # capture the answer
        for question in self.questions:
            answer = input("Question No {}: {}".format(index.self.questions(question), question.text) + ("\nYour answer: "))
        # check the answer
        # if the answer is right send back True
            if answer == question.answer:
                answer = True
                total_correct += 1
            # otherwise send back False
            else:
                answer = False
            self.answers.append(answer)
        # log the end time
            question_endTime = datetime.datetime.now()

        # send back the elapsed time, too
            elapsed_time = (question_endTime - quiz_startTime).seconds
            print ("Your time so far is {} secobds.".format(elapsed_time))


    def summary(self):
        # print how many you got right and the total # of questions. 5/10
        print ("You answered correctly {} out of {} questions!".format(total_correct, len(self.questions)))
        # print the total time for the quiz: 30 seconds!
        print ("You total time was {} seconds".format((self.quiz_endTime - self.quiz_startTime).seconds))
