How to sum an infinite series using chocolate.
Interesting article, thanks.
I wonder if anyone can give me a perspective on the relationship between my children and my brother's wife's descendants from a previous marriage?
My brother's wife was previously married, from which she has a son & daughter, and 2 x grandkids via the daughter. My brother, I guess is the step-dad of her grown up children, and the step-grandad of the grandkids - would that be correct?
Are his step-kids and step-grandkids any relation to me? Are they my niece & nephews in law, and great niece & nephew in law?
What relation are those people to my children? I guess the grown up kids are my kids cousins in law? What does that make the grandkids (closer in age to my own kids actually)?
