Hi alice 9;
Have you checked the other forums you have posted this question on? What did you not like about their answers?
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
