HP Prime G2 RPN use

[Vjsilva]

I am a G2 newbie and I have had the G2 only about a week so forgive me if this is a stupid question.
It is a very powerful calculator for graphing and solving, but sometimes I pick it up for a quick calculation, like an HP41 and it's different.

Does the G2 have a classic RPN interface?
I don't seem to be able to do something like:
1 ENTER 2 +

It appears like the G2 requires 1 + 2 ENTER, which is not RPN

Thanks,
Victor
