Dang, I just spontaneously lost my lunch money reading this.

If you go looking, most numbers have some kind of interesting property like this.
11 is the only 2-digit number that does not scare itself when looking in a mirror
Except for 12407.
Yeah fuck 12407.
Everytime I find a number related to someone I run it in wolfram alpha to check if its have something interesting. Like our professional registration number, my exboss has 3^7 and mine is prime.
What a shame it will only last a year. Enjoy it while you can number nerds!
The last one was in 1936
Oh shit... 2116 is gonna suck. This math is proof of a curse.
well all that good luck was spent on aligning all the math bullshit, so not surprising.
Is this a general rule? Because with my primitive checking, all sum of first n cubes add to the square of a triangle number.
1^2 = 1^3 = 1
(1+2)^2 = 1^3 + 2^3 = 9
(1+2+3)^2 = 1^3 + 2^3 + 3^3 = 36
...
Next one is not.
I don't know how to appreciate this.
I remember when I was supposed to be impressed that it was 11:11:11 on 11/11 11 as long as you just ignore the great big 20 in the year.
Well, at least the year 2025 isn't some boring number, like, say, 1729. What an unremarkable number that is.
The last two say the same thing in different forms
Ok, so I'm looking for someone who knows more than me about math to verify that all of this is accurate. Cause if so, this is really awesome.
Open excel (or any other spreadsheet app) or - at a push - the calculator app.
Type in 45 * 45. You will get 2025. Then try 44 * 44 and 46 * 46. You don't need a PhD to be able to do that :)
Then you can use the same app to add up 1 - 9 and get 45, which will verify most of the post.
The cube thing is a little more complex, but you should be able to work it out using the multiply and the memory function.
(I checked it before I posted it :))
I have terrible news for you. There is a whole swath of the population who do not care enough about math to ever get past step 1 (Open Excel.)
"Complicated" math is built out of simple math.
Squared and cubed are just ways of saying the same number multiplied by itself twice(squared) and thrice(cubed).
The reasons why they are called that is a reference to the most common use of that math, a square has 2 equal dimensions, and a cube has 3. So when someone asks what is the area of a square with side lengths of 5, it would be 5 x 5, or the volume of a cube with the same side length would be 5 x 5 x 5.
So taking this shorthand 2^3, and converting it into the full "simple math" equation it represents would be: 2 x 2 x 2.
The other main thing about complicated math is that there is an agreed-upon order in which we write math.
If you haven't gotten that far in math class, don't worry about it yet. The whole point of learning math is that it is best to learn it in the correct order. Generally, anyone struggling with math has accidentally skipped a step along the way of learning it. All the future things you learn are dependent on knowing the previous foundational knowledge.
So anyway, long story short.
This is saying: 45 x 45 = 2025 And that the result of 1 x 1 x 1 added to the result of 2 x 2 x 2 added to the result of 3 x 3 x 3 added to the results of 4 x 4 x 4 added to the results of 5 x 5 x 5 added to the results of 6 x 6 x 6 added to the results of 7 x 7 x 7 added to the results of 8 x 8 x 8 added to the results of 9 x 9 x 9 would be 2025.
And now you can see why they developed shorthand.
Here's one I found by accident myself. Multiplying all the odd numbers from 1 to 13 = 135135.
Just for completeness, add 0 and you have the complete set of single digits.

I'm here to warn you to stop adding to the importance of 2025. This cab only end in all Data from the universe discombobulating. We managed to stop the total sarcolobulational demise of everything that exists. But you must stop this thread now! Specially you Fred Robinson from Temecula! We believe in you! The penis image you must upload is 02324.jpeg. This triggers a simulated halt. This image has not been taken yet....the universe is on your hands....literally.
Wow, my parents were born in 1936 so they'll be interested to hear this. They absolutely LOVED IT when I told them they've been alive for more than one third of the duration of the United States!
