I have seen through the matrix. If you give me any number, I can intuit by eyeball whether the number is prime. I will explain my reasoning when possible.

Give me a number, and I will tell you if it is prime and how I intuited it.

(2^tree(3))-1

not prime. since i cannot offer any visual indicators, all i can offer is intuition.

Ok since you guys are no fun Ill reveal my secret. I have simply memorized the first 100 primes. 95% of responses will either be a small number that fits within that range (which I can remember) or it's an arbitrary series of numbers they just make on the spot usually 6-9 numbers long. If it's the latter I will simply ponder for a moment then say that it's not a prime and that it's divisible by 547 which the person has no way to verify. Statistically it's impossible that this approach doesn't work but if it doesn't then I simply skedadle.

prime?

>>16715940
Yes. This is one of the extremely rare primes that are divisible by two.

>>16715904
Not prime, sorry.

>>16715944
oh, taking into account complex numbers, neato

>>16715910
What do you mean "no way to verify"? What makes you think that?

>>16715910
Well?
