Query: Just great

I purchased the calculator for my son who attends high school. After reviewing the book that came with the calculator I was surprised with all the features it offers. I told him that many engineer students would love to have one. I wished I had one when I studied mechancal engineering many years ago. It is clear he will use at first just few of the features but as he decided for math-physics he will use it permanently for the next couple of years. No doubt it will also help him when he is at the University.
