Dear @acer 

It seems I didn't explain my question well

 How could I send you my mini Maple program to consider and check it if possible.

@Carl Love 

Thanks a lot for your reply but I have not used brackets in my program at all; but in my wonder it appears subscript  (For instance ) in substitution and I expect to have an identical value like 5.23232
