Define universe sets and based on them do what is required 4 subset exercises, consider a universe set and then show a subset of this with Set Notation by Extension and Comprehension

a universe set is the set that contains all the elements under consideration, usually denoted by the symbol U. Let's consider a universe set U = {1,2,3,4,5,6,7,8,9,10} 4 examples of subsets of U using extension notation : {1,2,3} ; {4,5} ; {6,7,8,9} ; {2,4,6,8,10} using comprehension notation : {x|x belongs to U, 5
