На финансовом калькуляторе HP 12C, который кстати разрешен на экзамене CFA, до сих пор используют метод обратной польской нотации. Алгебраический метод добавили на версии 12C Platinum.

Забавный рассказ написали о калькуляторе и экзамене CFA

For about 2 months before my boy Mark took the CFA (Chartered Financial Analyst) Level 3 exam, he didn’t go out at all. He’d go to work, come home, hit up the gym, and then study. That was it. Done.
“Going out is fucking lame, anyway,” he’d bark from the couch when I rolled up to his place on a Friday with two Lauren Conrad lookalikes. Sitting there in sweaty mesh shorts and a T-shirt, he’d wave a #2 HB pencil in the air dismissively. “Staying in is the new going out.” Then Lauren #1 would strut over to his fridge, showing off her perfect physique in the process. She’d take an ice cube and press it seductively against her collarbone as she closed her eyes and sighed in relief from the dense heat of New York City summer. I could see the Monte Carlo simulation running in Mark’s brain; Crystal Ball says—“you will get laid.” Then, right after his eyes entered back into his skull, he would look back down begrudgingly at his practice exam and mutter to himself, unconvincingly: “Whatever. That bitch is a 6, anyway…”
….
Excel Mobile, it speaks a pure, unambiguous language: Reverse Polish, a postfix notation that eliminates non-commutative issues. So instead of having to enter 7 + (5 * 2) - 5, you’d enter: 7 5 2 * + 5 -. Direct and to the point, crisp even—exactly how Bankers think and speak. I met a model from Kraków once, and although we hit it off physically, her English struggled, blocking us from that real “same plane” level I like to reach. So as a gesture of cultural sensitivity, I decided I’d speak to her in something closer to her native tongue. Over Lil’s Wayne’s Lollipop, I pointed between us aggressively and instructed: “You, friends, 2, TIMES PLUS… panties MINUS“ Boom. “Same plane,” said her eyes.
