1. What do they plan on using the calculator for (educational classes, engineering, fun, etc.)?
2. If it is for a class, what model calculator does the instructor recommend?
3. Do the already have experience with (or a preference for) RPN or RPL calculators?

If I don’t don’t mistake it the Prime do all the fonction but the RPN on it is not like a vintage calculator or the DM42.

We love RPN calculator all my friends got PCalc or Free42 or there iPhone.

We need sometime a graphing calculator (not always).
Is why that I am thinking that maybe the prime with a DM42 can be the answer.

The problem we got is with the prime we can’t use it in exam In Canada (Quebec) and they don’t want to told us why.
