-It is interesting to know that properties of left congruence and right congruence has the same basic properties. and more over the condition Na=aN does not imply an=na for n in N.
-I did not understand why (inverse a)Na=N does not mean that ( inverse a)na for n in N why it is that ( inverse a)na=n1 for n1 in N, why can't it be just n? Is it just a different symbol or it has some meaning?
