"Math Bug" Game

Very often we think back to school. How it was fun and interesting to sit in class and listen to the teacher. Some of us remember school breaks and fun games with our classmates. We invite you to go back to your elementary school desk and visit your math class. The teacher has prepared an interesting math test for you. First, choose a difficulty level. If you think you can do the hardest one by two, you can't. Start with the easiest one. On the screen of your gadget, you will see a mathematical equation. Look at it carefully, because there is one digit missing. Close your eyes and try to solve it in your head. Have you solved it - Then look down. You'll see numbers appear there, and one of them is the correct answer. Click on it with your mouse button. If you gave the correct answer, you will move to another level. Otherwise you will have to solve the equation all over again. With each level the tasks will become more difficult. With each correct answer you will get points to your account. If you answer incorrectly, you will have to start the game all over again.
