I'm absurdly excited to learn that 2024 = 2³+3³+4³+5³+6³+7³+8³+9³.

...and it's because:

2025 = 45², and

45=1+2+⋯+9, and

(1+⋯+𝑛)²=1³+⋯+𝑛³ !

@ddrake good opportunity to point out that checking this on an RPN calculator (like @pcalc ) is so nice!

@thomasfuchs Sometimes it’s just easier to get a physical calculator out!

This seems like it might be an extreme niche nowadays, but how many of you use an HP calculator (graphing or not) in RPN mode? Or, perhaps other calculator apps in RPN mode?

I was introduced to RPN by a civil engineer when I was in college, and I’ve never looked back. However, most other mechanical engineers I know don’t use it.

idiot,

@chrishuck yes rules for
Here are two in daily use. HP-15c collectors edition and HP-32sii teal/green version.

app4soft,

@chrishuck Here are JRPN 15C & JRPN 16C (Jovial Reverse Polish Notation Calculators) — opensource cross-platform simulators of HP-15C & HP-16C with mode.
Both apps available for Android, Linux, Windows, MacOS, iOS and as Web: https://jrpn.jovial.com/
This apps actively maintained.

Hey lovely Mastodon folk. I've just released an HP-35, HP-45, HP-80 simulator called HP-1973 to celebrate the 50th anniversary of the HP-45 calculator. (Free) standalone versions for Mac and WIndows (no need for any Python installation or knowledge) & Python source for Linux. It's been a coding marathon, so it'd mean a lot to me if you could boost this post, so it gets in front of the right people. Download here: https://sarahkmarr.com/retrohp1973.html Enjoy. #retrocomputing #calculators #python #coding #rpn

In praise of Reverse Polish Notation (RPN) with Python or C

For whatever reason, RPN didn’t really succeed in the general marketplace, and you might wonder why it was ever a thing. The biggest reason is that RPN is very easy to implement compared to working through proper algebraic, or infix, notation. In addition, in ...continues
