I really don't understand, why you quoted me?
Its not a problem for me to deal with such questions and the way i was doing was easier than your's.
Both methods are exactly the same.. one looks shorter as a lot of the steps can be done mentally and not written down.
Correct, both are the same, but i was surprised to be quoted, may be if the post would have been directed to the OP then it would have made a bit of sense.
