Another year has gone by, so on the 11th, I'll be celebrating another year survived on this earth. Last year I did a lot of stats about the number 41, but I feel like thanks to The Hitchhiker's Guide to the Galaxy and 420 blaze it I don't feel like looking into weird facts about this number. Oh, but I can leave you this year related mathy fact:
2025 = (20+25)² = (1+2+3+4+5+6+7+8+9)² = 1³+2³+3³+4³+5³+6³+7³+8³+9³

Last year I dumped a lof of bundle leftovers, free keys and stuff on you, so this year I went the other direction and bought you a few unbundled games. Right now there are 10 GAs, level 2-8, though the level 8 ones are public, just to be different. Some are slightly hidden, just to test how much of a difference that makes, and they are all bot protected. To find out how, you can either think about the title or compare the public ones with my profile I guess.

GAs last until I expect to be up and about on the day after my birthday 😉

It would be interesting to examine mathematically the history of calendars around the world.
(I wouldn't do that, though, because it would make my plate boil.)

I am a bit of a number-nerd, but that article made my eyes glaze over 🙈

2025 = (20+25)² = (1+2+3+4+5+6+7+8+9)² = 1³+2³+3³+4³+5³+6³+7³+8³+9³

The last part is wrong. 1³+2³+3³+4³+5³+6³+7³+8³+9³ = 285

Edit: oops, cubes not squares

It's not easy to see depending on font, but the things in brackets is raised to the power of two while the last has all numbers raised by the power of three, you seem to have worked with twos there as well. The last two entries are are equal for all 1...n due to Nicomachus's theorem

Oh, I thought the superscript 3s were 2s (must be time for me to get some new glasses)! I wasn't aware of the theorem either - thank you for the link. So those around in 1000 years will see:

3025 = (30+25)² = (1+2+3+4+5+6+7+8+9 +10)² = 1³+2³+3³+4³+5³+6³+7³+8³+9³+10³

Weird, I just mentioned to my students yesterday the thing with the sum of the cubes, namely, that

(1+2+3+...+N)² = 1³+2³+3³+...+N³

works for any N. It is indeed a remarkable little thing!

Cheers!
