What answer is correct for n=5 and n = 6?

My answers are:
2^-6 = 1.563E-2
2^-5 = 3.125E-2
Are the correct?
If your 545 is accepted, send it for me to medv@roller.ukma.kiev.ua.

I tried a lot, but got WA. Help me, if you can.

Thank you.

10200 I have WA

To my suprise my program says that there is no prime numbers among values n*n + n + 41 for 1000 < n < 9999. I think I am wrong when testing the primes.
Please, send me such n that 1000 < n < 9999 and the value n*n + n + 41 is prime.

Can somebody tell me why I get WA and what is the best way to write long arithmetic (I use Borland (Turbo) Pascal, the maximum type here is Longint). (* @JUDG...
