I recommend re-reading the OC and the replies.

what is the OC? whose replies??

I think I gotta somehow get a better understanding of Mersenne and Eisenstein primes, but I don't like jumping through 'bureaucratic'-academic hoops to get things explained to me. it's only numbers, I have other things to do

What the original commenter dislikes is that a bunch of "brilliant" mathmaticians can't instantly recognize that any number ending with 2 or 5(except 2 and 5) can't be a prime.

I.e

999999999999995%5=0 999999999999992%2=0

Thus they are not prime numbers.

If number end in 2 or 5, is divisible by 2 or 5. So number ending in 2 or 5 cannot be prime. Math no hard to understand!

but this is only because 10 in ten in decimal system

but the numbers are not (only) how they're written down!

meh...

Everything you've written is gibberish in spanish, why did you do that?

cuz it happens to be the first spoken language I learned?

does this answer your question? if not, maybe this can help: https://www.youtube.com/watch?v=BdOtR2A5agc
