For Maths fans, 2025 is a square.
45² = 45 x 45 = 2025
Also,
9² x 5² = 2025
40² + 20² + 5² = 2025
My favourite?
1³+2³+3³+4³+5³+6³+7³+8³+9³ = 2025

[ \sum_{n=1}^{N} n^2 = \frac{N(N + 1)(2N + 1)}{6} ]
N = 45
[ \sum_{n=1}^{45} n^2 = \frac{45 \cdot 46 \cdot 91}{6} = 2025 ]
1³+2³...
My favorite too!
2025 = (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9)²

you just have to work it out on paper with a pencil.
(20+25)² = 2025
(1+2+3+4+5+6+7+8+9)² = 2025
Happy for you to take all the credit.
Jk 🫶🏻
Sorry, I'll get my cape.
I stick with prime numbers only. 🙃
I do love the numbers 3 and 13.
27² + 36² = 45² = 2025
(1+2+3+4+5+6+7+8+9)² = 2025
202.5×8+13²+5³+4²+7²+7²-3=2025
2025 = (5^2)x(3^4)
Lord have mercy!
45, 4+5=9
666, 6+6+6=18,1+8=9
45 = the Antichrist
(to which there is a plethora of possible rejoinders) ...
So it's a Anno game year ;)
I did and it was cool. Thanks.
Hitler started invading (Rheinlandbesetzung)
(1+2+3+4+5+6+7+8+9)²=2025
Trump just started, signs don’t look good
Hence-
2+0+2+5=9.
Then again, 2+0+0+7=9.
I know nothing lol
I never said I believed in it lol
“Family income in the US has gone from 10K in 1971 to 55K a gain of 5.5x
however,
The cost of a car has gone from 4K to 48K, an increase of 12x
The cost of a house has gone from 25K to 357K, an increase of 14x
The cost of healthcare has gone from $400 to $15,000, and increase of 37x.”
81 + 25 = 106
81 x 25 = 2025
Thousands | Hundreds | Tens | ones
2 | 0 | 2 | 5

Is there a cubed version of 9! factorial?!
(1+2+3+4+5+6+7+8+9)² = 2025
1+3+5+7 = 4x4
