 Oct 28 awarded Famous Question Sep 28 awarded Famous Question Aug 21 revised Can I keep adding more dimensions to complex numbers? deleted 202 characters in body Aug 21 awarded Popular Question Sep 16 comment Congruence modulo n where one side is equal to 1 OK thanks, I just found the terminology and formulation used in the book quite confusing. Sep 16 accepted Congruence modulo n where one side is equal to 1 Sep 15 comment Congruence modulo n where one side is equal to 1 Let me quote the book: Two numbers are said to be congruent modulo n if they both have the same remainder when divided by n. The remainder of a number a when divided by n is also referred to as the remainder of a modulo n, or simply as a modulo n. So as far as I understood it, they're saying that $a^{n-1}$ and $1$ are congruent modulo $n$, which means that they have the same remainder when divided by $n$. So I'm not sure in your answer...

For R3 you simply define a number j that has the property j^3 =− 1. - isn't that -1? Mar 14 comment Any natural number is greater than or equal to its product of digits. @Hawk I misread the question as "lower than or equal to" - sorry! Mar 14 comment Any natural number is greater than or equal to its product of digits. I don't get this. If a number has 0 as a digit, wont its product of digits also be 0?
