The <em>quotient</em> operator is both an infix and prefix binary operator that 

returns the quotient of its first argument divided by its second. It is 
also a unary 
<A HREF=r37_0101.html>recip</A>rocal operator. It is identical to <em>/</em> and
 

<A HREF=r37_0030.html>slash</A>.

&lt;expression&gt; can be any valid REDUCE scalar expression. Matrix 
expressions can also be used if the second expression is invertible and the 
matrices are of the correct dimensions.

<P>
The <em>quotient</em> operator is left associative: <em>a quotient b quotient c
</em> 
is equivalent to <em>(a quotient b) quotient c</em>. 
<P>
<P>
If a matrix argument to the unary <em>quotient</em> is not invertible, or if the
 
second matrix argument to the binary quotient is not invertible, an error 
message is given.
