Best ResponseYou've already chosen the best response.1google the phrase: "closed under addition" and you should get a rough idea, or at least a basis to work from.

Best ResponseYou've already chosen the best response.1consider 'closure' like being locked in a room .. nothing can get in or out. the only thing we have to work with, is what is in the room with us. now we are told that all we have to work with, is whole numbers, and addition. if thats all we have to work with, then that is all that can appear in our work.

Best ResponseYou've already chosen the best response.0So in this case, closure under addition means for all . This set isn't closed under addition; consider . Closure under multiplication in this case means for all . This set is closed under multiplication; simply write out all possible products of elements

Best ResponseYou've already chosen the best response.0In mathematics, the natural numbers (sometimes called the whole numbers) are those used for counting (as in "there are six coins on the table") and ordering (as in "this is the third largest city in the country").
