, 12:04, November 16, 2008Characteristic of a field
I don't like the notation n*r, without any introduction, it's rather repeated addition. Maybe a subtle point, but it is different from the multiplication of the ring. For the moment, I'll let it stay... --[[User:BRichtigen|BRichtigen]] 18:26, 14 November 2008 (EST)

==Characteristic of a field==
I'd prefer to introduce the characteristic of a field via the example section, i.e.:
*If '''R''' is a field, i.e., a ''ring wiht unity'' wherein every non-zero element is invertible, then the characteristic is zero or a prime-number
