Press the green flag to start and start over. DO NOT type letters instead of numbers because it won't work.If you want to you can check the answer with a calculator. Also, on the first question, if you pick a number that is not stated to give, it will say invalid answer and ask you the question again until you give a valid answer. And it also might be laggy.
