    welcome to Multiplication Game
    Here is how to play:
    You choose how many rounds you would like to play and each round you will get one question
    You type the answer that you think is right and press enter 
    The game will tell you whether you have gotten it right or not. 

    One of our speciality of this game is that it can show you the history and you can revise 
    on the ones you have gotten wrong. 

    Have fun learning!
