RE: prime number challenge
I was thinking more of the folks that can look at a photo of pebbles or some such, and more or less instantly give an accurate total of how many there are.
So would it even be possible theoretically for a person to look at a 10 digit number and ascertain in a few seconds whether or not it's prime ?? 2speed HP41CX,int2XMEM+ZEN, HPIL+DEVEL, HPIL+X/IO, I/R, 82143, 82163, 82162 -25,35,45,55,65,67,70,80 |
