The expression appeared on the command line. I then moved to the 1000 and added a zero. Then I hit Enter again and the new expression was calculated. I'm using the 2.1.14575 (2021 04 28) Beta.

Your method probably works in "Textbook" mode, not in "RPN" mode. In "RPN" mode your method works only if you first hit "shift" + parenthesis: ' '. Am I wrong? Sincerely, Roberto

Ah. I was in Algebraic mode. I never use RPN mode on the Prime since it's just kind of grafted on like an afterthought and not really an integral part of the calculator.
