There is no attachment/s.
So, need to connect via [netcat](https://en.wikipedia.org/wiki/Netcat/) with given source.
Quick note — if you want to solve it yourself, give yourself some time now — later it will be too late, because you will already see the solution; that means no such fun:P
The sample of interaction you can see below:

It seems like this challenge is asking for two numbers
n1 and n2
where the following condition holds true:
n1*10+n2*10 ≠ (n1+n2)*10
You can/could check many use cases. I like this task, because as a [Software Engineer](https://en.wikipedia.org/wiki/Software_engineering) I was fixing connected with this [PBI](https://learn.microsoft.com/en-us/azure/devops/boards/work-items/agile-glossary?view=azure-devops) issue years ago where the point was [floating point error](https://stackoverflow.com/questions/588004/is-floating-point-math-broken).

I hope you enjoy!
