Can Non Menbers post in this area?
Yes, you can but you should stick to the topic. It is like a miniature forum by itself. If you want to post there it should be a post about a programming problem.
In mathematics, you don't understand things. You just get used to them.
I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.
OK thanks for the Reply.
