Best ResponseYou've already chosen the best response.2the big R means "real numbers" a real number is any decimal number you can think of eg: 2.7562

Best ResponseYou've already chosen the best response.2the big Z means "integers". Why didn't they use capital i? well i is reserved for later math courses, so Z is used instead but why Z? It turns out that `Z is for Zahlen  the German word for integers` http://mathforum.org/library/drmath/view/53922.html I guess when the math notation was developed, a German mathematician was the one who came up with the set of integers

Best ResponseYou've already chosen the best response.2well we wouldn't use R because we don't want real numbers we want integers

Best ResponseYou've already chosen the best response.2it states ` less than or equal to 1` the key part to look out for is the `or equal to`

Best ResponseYou've already chosen the best response.2the one with \[\Large \{xx\in\mathbb{Z} \ \text{ and } x \le 1\}\] whichever one that is
