Funny Things About the Number 2025

2025 is a pretty cool number, as far as numbers go. It has some fascinating properties—so fascinating, in fact, that it might make cameos on some future math tests because math teachers just can’t resist numbers as remarkable as 2025. (Neither can competition math problem-writers; heads up, Lakeside’s math club!) Without further ado, here are ten intriguing facts about 2025!

1^3 + 2^3 + 3^3 + 4^3 + 5^3 + 6^3 + 7^3 + 8^3 + 9^3 = 2025

This exact fact actually did show up in a MathCounts trial I took! I now feel extremely validated in the time I “wasted” (a.k.a. productively spent) repeatedly Googling “funny things about 2025.”

45^2 = 2025

Let's be real—this will definitely show up on at least one math test in 2025, I promise. Why? Because math teachers like being right so much, they can’t resist squares. (See what I did there?)

It’s a tau number because it’s divisible by its number of divisors. That is to say, 2025 has fifteen divisors, and 2025 is divisible by 15.

I have no commentary on this, except that “tau” is pronounced “toe,” which is why it would be perfectly normal to announce that one loves toes in the middle of math class. (Okay, I’m joking. It’s pronounced tow, rhymes with cow.)

2025 = 3^4 * 5^2

I admit, this fact isn’t groundbreaking. But it has the numbers 2, 3, 4, and 5, which is fun! (Fine, I’m running out of clever commentary…)

2025 in base 13 is BCA.

Fun fact about me: I got rejected from BCA (the school). I’m told everyone gets in, so that stings a little… but maybe it was just my luck (thirteen’s pretty unlucky, after all).

The length of 2025’s hailstone sequence before it repeats is 34.

I don’t have a joke here, but you better laugh anyway because I had to spend my precious time—and a perfectly good poem as scratch paper to bash out the arithmetic. (Sorry, Mr. GS.)

What is the hailstone sequence, you ask? Well, take any number. If it’s odd, multiply it by three and add one. If it’s even, divide it by two. Repeat. People think but have yet to prove that this sequence will always end with a repeating 4, 2, 1, 4, …

People born in 2025 are generation beta.

That’s wild. Two generations after mine? I can’t even. Honestly, I feel old now…

The sum of all the divisors of 2025 is 3751. 2025 in base 8 is also 3751. 

Coincidence? Probably. Cool? Definitely. (Perfectly placed in this list? You bet.)

For the Swifties out there… 2025 fortnights is approximately the span of a human lifetime.

Attention, Swifties: this is your fact! This article has definitely devolved. It started as pure math, and now it's… Taylor Swift? I mean, I guess Tay-Tay has a connection to math. Has anyone ever heard of the Taylor Series?

Next year is 2025.

Stop judging. Yes, I ran out of ideas. But let’s be honest—if you’re like me and you still haven’t broken the habit of writing 23 instead of 24 when adding dates to your assignments, this will come as a shock.

No? Just me?

Okay then.
