Feature: Calculator

  Scenario: Add two numbers
    Given I have a calculator
    When I add 5 and 3
    Then the result should be 8

  Scenario: Subtract two numbers
    Given I have a calculator
    When I subtract 10 from 15
    Then the result should be 5

  Scenario Outline: Multiply two numbers
    Given I have a calculator
    When I multiply <a> and <b>
    Then the result should be <result>
    
    Examples:
      | a  | b  | result |
      | 2  | 3  | 6      |
      | 4  | 5  | 20     |
      | 6  | 7  | 42     |
