142857=宇宙密碼
                            大家去試吓用142857+7次
                            就等於(999999)咁代表放假
                            大家又去試吓用142857*142857
                        算式如下:
                              (142857*142857)就係(20408122449)
                              再次將20408+122449
                              就會再次等於返(142857)喇!
