Hoy, 20 de enero…
– Sí, tienes razón, de dos mil veinticinco.
A decir verdad, había encendido el ordenador para escribir:
“¡Hola, Mundo!.
¡Cómo estás!
Mis mejores deseos para 2025”
Y al escribir el 2025…
¡Qué año! Digo, ¡qué número! El 2025. Si le hacemos la raíz cuadrada da exacto: 45. La última vez que pasó esto… no nos fue nada bien… mira y verás.
– Sí, tienes razón de nuevo, ¿nada bien para quién?
¡Qué número! Si sumamos sus cifras nos da 9 que sólo es divisible por 3, además de por 1 y por sí mismo, pero eso no tiene mérito salvo que seas un cero. Quédate con el 9 y con el tres y ahora ve elevando al cubo, es decir a 3, los numero del 1 al 9 y… ¿qué te da?
Pues sí: 1³ + 2³ + 3³ + 4³ + 5³ + 6³ + 7³ +8³ + 9³ = 2025.
Además, si nos fijamos en el cuarenta y cinco es la suma de los número del 1 al 9 por lo que nuestro dos mil veinticinco también podemos escribirlo como:
(1+2+3+4+5+6+7+8+9)²
– No, no me estoy volviendo cabalista pero desde hace años me considero chanchiter y todo se pega.
– Sí, ya sé, que vaya manera de volver después de tanto tiempo…
¡Qué tal por ahí! ¡Saludos!
Por cierto, la IA que han incorporado en WP me ha recomendado el título: «Chanchitismo y matemáticas: qué significa el 2025» .
El cuidado en la palabra 
Dear José, Welcome back to the blogging world. I am so glad for this. But I can see, not easy to understand your first post. My mind confused. Maybe I get older more in 2025. Similing. Anyway, let me share my points that I want to ask some questions. Because I want to understand.
a pig and everything sticks»…. why and what… ? Is it a phrase,…
Finally «What means 2025?»
Dear José, first of all, nothing makes a sense to me in mathematic… Actually I love mathematic, but the meaning of 2025 shouldn’t be in there. Of course this is my thought. Among the numbers, there should be several meaningful points, I can’t deny this. But the subject is about human life, we can’t express or explain with numbers… 2025 started with new and changed things. New is good. Change is good. But also show me I get older more. And all healthy problems slowly start… My Bloog pressure is high and new medication started. Before we didn’t want to have a blood pressure monitor, but now we have. And some others too,… But my most important point for 2025, everything to be fine in my own country and not to be said everyday when I read or hear the news… Still we have a chance for this, I mean to change all wrong things,…etc. We can stop the murders of women and children… And to get back our international laws, ensuring law and justice,…etc. In our very recent past we have so tragic events, sad events… I hope and wish all bad things stay in the back…Personally, my expectation from the new year is a healthy and peaceful old age. That’s all.
Once again Welcome back dear José, Thank you, have a nice days in this New Year, Love, nia

Dear Nia,
First of all, I would like to apologize for my delay in answering you and also thank you for your comment, which, as always, invites us to delve deeper into the issues and reflect.
The title of the post is a bit of a code. The «C23» is related to 2025 and refers to the fact that 2025 is a centered octagonal number, which means that it can be represented by concentric rings around a central point, forming a regular octagon. Specifically, 2025 can be formed with 22 concentric octagonal rings around a central point. And, in mathematical notation, it can be written as C23.
When I wrote:
«What a number! 2025. If we square it, it’s exactly 45. The last time this happened… things didn’t go well for us… just watch and see. 45×45=2025… but what was the last time? Do you mean 2024 or…?»
I’m referring to the fact that the last time it happened, 44 x 44 gave 1936, which in the history of Spain was a terrible year in which the Spanish Civil War began, which was won by the military uprising that overthrew the democratically elected government and which continued with four decades of terror of military dictatorship. Now, 2025 doesn’t look good on a global level with the rise of far-right ideologies that are once again inoculating hatred among human beings.
The following:
«1³ + 2³ + 3³ + 4³ + 5³ + 6³ + 7³ +8³ + 9³ = 2025…..» is a mathematical curiosity about the number 2025.
The term «Chanchiter» is difficult to translate for Google ha ha ha…
Actually, it is a nod to a mathematics podcast that I follow and is called «Los tres chanchitos» [Chanchito means little pig] and the followers of the podcast are usually called «chanchiters». A mathematician called Clara Grima participates in the podcast, whom I have been following for a long time and I love. I was able to greet her at a conference she gave in Palma and whose popular books I have read.
Finally, I wanted to play a little with the artificial intelligence that WordPress has incorporated into its editor and the title it suggested for the post was: «Chanchitism and mathematics: what does 2025 mean» which is quite accurate.
Thank you very much again, dear Nia, and I hope that soon your health problems will be resolved and that your blood pressure will be under control. I also hope that sanity and human rights prevail in world politics, which, for now, are in a bad way.
My best wishes for 2025 for you and all yours.

Thank you so much for your explanations. I understand now, but also I understand there are some points that I didn’t know. About 2025, yes we all want world run in positive ways… And sure, I hope and wish a better 2025 than past years… But I am not hopefull for my own country. Anyway dear Jose, Thank you again for your time, sometimes really I am being sad that I don’t know your language, and Thank you for your nice wishes. Have a wonderful days, Love, nia
