hi,
Table shown is completed to define 'associative'
binary operation * on S={a,b,c,d}.
*|a|b|c|d
---------
a|a|b|c|d
---------
b|b|a|c|d
---------
c|c|d|c|d
---------
d|d|c|c|d
The operation * is associative iff (a*b)*c=a*(b*c) for
all a,b,c element of set S.
So can (a*d)*d=a*(d*d)=d considered as associative
over * for this case as per definition?
Regards Sarath.
