Iff

Revision as of 00:23, 7 July 2006 by IntrepidMath (talk | contribs)

Iff is an abbreviation for the phrase "if and only if." If and only if proofs often contain two parts. The first is the "if" part, which is reletively straightforward. The second is the "only if" part. To prove this, you need to show that the to prove is only satisfied by the given. This is typically more difficult than the "if" part.
