Subsets & Sets Math Help Game Tips: - In this game, the rectangular shape 'U' represents the Universal set of members for all possible sets. - If set P is a circular region inside U, then the set 'not P' is the region outside circle P and inside U. The set 'not P' refers to all members of set U that are not members of set P. - When selecting members from two sets, the word 'and' refers to the overlapping region P and Q. P and Q is called the intersection set. If set P is completely inside set Q, then P is called a subset of Q resulting in (P and Q) = P. If set Q is completely inside set P, then Q is called a subset of P resulting in (P and Q) = Q. If set P and set Q do not overlap , then they are disjoint sets with the result (P and Q) = empty = Null set. - When selecting members from two sets, the word 'or' refers to the entire region including P or Q. P or Q is called the union set. [The 'exclusive or' concept is not used in this game.] If set P is completely inside set Q, then P is a subset of Q resulting in (P or Q) = Q. If set Q is completely inside set P, then Q is a subset of P resulting in (P or Q) = P. - It may take a minute to load the game at dial-up speeds. - The game can be played using the mouse by itself or using the keyboard by itself. - The score report automatically appears after you have made 10 choices. - The Venn Diagram score is based on your choices only and does not count the bird hits. - The Game score is reduced by the number of bird hits. - If the game doesn't respond to keyboard input, click inside the game area to reset the game's focus. - The game speeds up as your score increases. Adjust this with the - and + keys. - Refresh/Reload the web page to start over again. |
