Scenario: Add two numbers

   Given I have entered 50 into the calculator
   And I have also entered 70 into the calculator
   When I press add
   Then the result should be 120 on the screen

    Given I have entered <FirstOperand> into the calculator
    And I have also entered <SecondOperand> into the calculator
    When I press add
    Then the result should be <Result> on the screen
    |FirstOperand|SecondOperand|Result|
    |20          |30           |50    |
    |60          |40           |100   |
