Satisfactory.
This thing is amazing--it will solve problems right from the math book. It has capabilities I will probably never use. Being used to the old HP-48 I am finding it difficult to do operations that were easy on the old HP. This is a matter of getting used to it. The HP had a great book that explained everything. Documentation on this thing is poor to very poor. Like all of these devices there are features that are inexplicably perverse. It seems you can store a function under a name, but you can't retrieve or edit it. I've looked high and low and tried everything I can think of. A variable, yes, Function, no. There are ways around this though. If you want something that will do algebra problems for you, this is it.
