This is the Life Advice Fairy! Insulting those from whom you ask help is not generally a good strategy for getting help! Although there may be rare instances in which it works, such as when teachers are being paid to do it, it is much less likely to work on an Internet forum whose helpers receive no compensation other than joy and fuzzies for doing it!

Additionally, when you say "I've calculated something", you should say what you've calculated it to be! That way helpers know you've actually tried the question rather than immediately fishing for hints! It is considered helpful to post complete questions too, possibly in picture form, so that we know you haven't mis-stated something and/or aren't missing something obvious!
