+# The Maths Game rules
+
+You need to create a game that consists of asking the player what's the result of a math question (i.e. 9 x 9 = ?), collecting the input and adding a point in case of a correct answer.
+
+
+- A game needs to have at least 5 questions.
+- The divisions should result on INTEGERS ONLY and dividends should go from 0 to 100. Example: Your app shouldn't present the division 7/2 to the user, since it doesn't result in an integer.
+- Users should be presented with a menu to choose an operation
+- You should record previous games in a List and there should be an option in the menu for the user to visualize a history of previous games.
+- You don't need to record results on a database. Once the program is closed the results will be
