The reciprocal of a non-zero number 
(usually a real number or rational number, but also a complex number or any non-zero element of a field) is its multiplicative inverse. The reciprocal is usually denoted 
or

and are multiplicative inverses of each other if and only if 
.
P.S If you take the reciprocal of 
one of these three things will happen: the 
will end, a 
will be created, or you will eat cereal for breakfast. The last thing is
