I'll explain it this way. 1. Click the green flag. 2. Tell Mr. Batthematics your name. 3. Answer Mr. Batthematics's addition questions. If you get five correct answers, your life is saved. But if you one answer wrong, the bat kills you.
To come up with the name "Batthematics" I took the word "Mathematics" and changed the "ma" to "bat" because they sounded alike. So I came up with Batthematics. Please comment on this project! I love comments.
