(mod p)?

Recommended Posts

I think that's modular arithmetic, where you have a limit, the modulus, where the numbers "restart", but I'm not sure. Basically, it's like a clock: if it's 21:00 and you add 5 hours, it won't be 26:00 but 2:00 because the modulus is 24.

So, in this case:
26 ≡ 2 (mod 24)

So the p in (mod p) is the modulus, the limit where the numbers wrap around. I think there's more to it, but I can't remember. Edited by Referos
