dence, associativity of the terminal determine what happens.</p><p>

An associativity is assigned to each terminal used in the
precedence/associativity declarations.  The three associativities are
<tt>left, right</tt> and <tt>nonassoc</tt>  Associativities are also
used to resolve shift/reduce conflicts, but only in the case of equal
precedences.  If the associativity of the terminal that can be shifted
is <tt>left</tt>, then a reduce is performed.  This means, if the input
is a string of additions, like <t
