+Feature: Division
+  In order to avoid silly mistakes
+  Cashiers must be able to calculate a fraction
+
+  Scenario: Regular numbers
+    * I have entered 3 into the calculator
+    * I have entered 2 into the calculator
+    * I press divide
+    * the result should be 1.5 on the screen

+# language: en
+Feature: Multiplication
+  In order to avoid silly mistakes
+  Cashiers must be able to multiplicate numbers :)
+
+  Scenario: Regular numbers
+    * I have entered 10 into the calculator
+    * I have entered 4 into the calculator
+    * I press multiply
+    * the result should be 40 on the screen

+# language: en
+Feature: Addition
+  In order to avoid silly mistakes
+  As a math idiot
+  I want to be told the sum of two numbers
+
+  Scenario Outline: Add two numbers
+    Given I have entered <input_1> into the calculator
+    And I have entered <input_2> into the calculator
+    When I press <button>
+    Then the result should be <output> on the screen
+
+  Examples:
+    | input_1 | input_2 | button | output |
+    | 20      | 30      | add    | 50     |
+    | 2       | 5       | add    | 7      |
+    | 0       | 40      | add    | 40     |
