December 5

I lost track of my HP48GX about the same time we went to New Mexico on vacation more than two years ago and I figured it was gone for good. Every time I found myself trying to use Reverse Polish Notation on a normal calculator, I'd think about it, wondering if I'd ever see it again.

When I came upstairs to get my coffee this morning, I was shocked to see my faithful HP on top of the microwave. I'm grateful that Luke had (for some yet unknown reason) cleaned out behind the free-standing kitchen cabinet and come upon it.

He was hoping that I'd let him use it for homework until he came face to face with RPN. After struggling with that for five minutes, he decided maybe times tables were easier memorized after all.
