Ошибка при нажатии кнопки Telegram Bot

При нажатии кнопки Addition, которая генерирует пример с арифметическим действием сложение пользователю, выходит вот такая ошибка

TypeError: math_operation() missing 1 required positional argument: 'args'

А вот сам код от бота

import telebot

bot = 'token'


@bot.message_handler(commands=['game'])

    if message.chat.type == 'private':
        if message.text == '/game':

            addition = types.KeyboardButton('➕ Addition')
            markup.add(addition)

            bot.send_message(message.chat.id, 'Welcome!', reply_markup=markup)
        elif message.text == '➕ Addition':
            addition1 = (int(random.randint(1, 10)))
            addition2 = (int(random.randint(1, 10)))
            answer = addition1 + addition2
            args = (answer, )

            msg = bot.send_message(message.chat.id, f'Solve the example:\n{int(addition1)} + {int(addition2)}')
