   Negation. Sometimes in mathematics it's important to determine what the opposite of a given mathematical statement is. This is usually referred to as "negating" a statement. One thing to keep in mind is that if a statement is true, then its negation is false (and if a statement is false, then its negation is true).

   The statements diagonally opposite each other are negations. Here are some examples of quantified statements: Symbolically, the universal statement “All A are B” can be written as “ ÊA are B”, or “ ÊA B”. The existential statement “Some A are B” can be written as “ Ì T Ð # so that T Ð $”
