Happy New Year everyone. I having pleasing maths to share (courtesy of my 18yo who saw it on insta). 2025 is the only square this century! 🤓

Saw it as well ...seen this?

Please thank your 8 yr old most sincerely.

@astroroyalscot.bsky.social Happy New Year!

Does that make February 14th ❤️ Square Root Day 2025?

Note for the bemused: this is _ number representation as used in RISC OS.

It’s also (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9)^2

🤓 How did I not know that 2025 was such a pleasing number before today!! 🤗

Because you're not a mathematographist?

Indeed and 2116 is the next one!

My mother and father now living in their second square year, something few of us get to do. I’d have to live to 154.

Happy MMXXV to you! 🙂
