Hi LittlePeng9 ! Happy christmas ! Thks for the precision in part 1 although I don't really consider it to be a mistake. But, concerning part 2, I must disagree. It seems strange, but adding 1 or 2 or more elements to an infinite set does not change its cardinality. The number of elements in the infinite set REMAINS the same. . The cardinality remains the same. N(0)+ 1 as a new cardinality on its own does not exist !!
