Anyone willing to take a stab at the high school math exam, Russian style?

[Al B. Sure!]

Please tell me each of these questions is a joke, and that you really have heard of exponentiation and equations in multiple variables.

Otherwise: what the hell is wrong with you? How did you get a degree in finance, an allegedly quantitative subject?

So n is a different variable? Well I'm clueless how to solve it.

How do I solve an equation with multiple variables when there are exponents and factorials? I was taught this in high school but I don't remember this.

Alby, sometimes I think you wake up each morning wondering aloud to yourself how you can look even more retarded on the internet.

HC, sometimes I think you wake up each morning wondering aloud to yourself how you can look even more like a pompous ass douchebag on the internet.


I don't know how to solve it. I don't have the base knowledge of what to do with exponents and factorials. I don't see how that's opportunity for scorn. Let's see how many people on Apolyton know how to do this so you can ridicule them.

[Al B. Sure!]

the arithmetic ones are easy. the rest, i have no idea. i suck at maths and school was more than a decade ago.

Hey better watch out, Cockney. You're going to get called a ******.


I haven't seen anything like this in college. And I placed out of required university math for finance.

Would he act indignant and defensive if someone said he sucks at math? I doubt it.

Holy ****, mine definitely has. How in the hell did I imagine a cube with 8 faces? :suicide:

The official solution onodera posted uses arithmetic sequences. I just saw that n was probably 5 and so k had to be 3, and a little bit of tweaking revealed that there probably weren't any other solutions.

It's in Russian so I don't understand the explanation.

How did they get to n = 7m in this version with different numbers?

[Kuciwalker]

The answers onodera posted appear to be for a slightly different version with different parameters. As I said, they used arithmetic sequences.

What does arithmetic sequences mean? Trial and error?

Alby, this is math I learned literally in 8th grade...

[Kuciwalker]

I should clarify that they are perhaps using some other sequence-based argument. I just saw the a[n], a[n-1] etc. in the answer page (which I can't otherwise read) and assumed.

And I did, too. Haven't seen it since at least high school.
