+Feature: Complex Addition
+  In order to avoid silly mistakes
+  As a math idiot
+  I want to be told the sum of two numbers
+
+  Background:
+    Given I have a calculator
+
+  Scenario: Add two numbers
+    Given I have entered "50" and "75" into the calculator
+    And I have entered 70 into the calculator
+    When I press add
+    Then the result should be 120 on the screen
+
+  Scenario Outline: Add three numbers
+    Given I have entered <number1> into the calculator
+    And I have entered <number2> into the calculator
+    And I have entered 120 into the calculator
+    When I press add
+    Then the result should be <number3> on the screen
+
+    Examples:
+      | number1 | number2 | number3 |
+      | 10      | 20      | 150     |
+      | 20      | 40      | 180     |

+    Given I have entered 50 into the calculator
