Thank you so very much. There are a couple more questions that I just dont know how to answer but I can't afford $60 for each of them. However, I TRULY appreciate your help. He lost his first grandchild in delivery and he has not had any time to study or work and I am just a mathematician but that was 30 years ago. If you have any extra time, I attached the last couple of questions if you have time but again, I don't have any more money. I am out of work myself but this is my friend and I am trying my best to help him.
