Consider the following statements :   `1.` `Nuu(BnnZ)=(NuuB)nnZ` for any subset `B` of `R`, where `N` is the set of positive integers, `Z` is the set of integers, `R` is the set of real numbers.   `2.` Let `A={n in N : 1 ge n ge 24, n "is a multiple of" 3}`. There exists no subsets `B` of `N` such that the number of elements in `A` is equal to the number of elements in `B`.   Which of the above statemetns is/are correct ?
