what is a an abelian group?
an abelian group is a group whose operation is commutative
i dont get it??
these is the commutative property of addition \[ \large a+b=b+a \] if u have a general operation, say *, then it would be \[ \large a*b=b*a \] when this holds in a group, the group is called abelian
k.....i got it...then what is a group?
a group is a set with an operation * which satisfies the following conditions: (i) given any \(a\) and \(b\) in the set, \(a*b\) has to bet in the set closure property (ii) \(a*(b*c)=(a*b)*c\) associative property (iii) there is an element \(e\) in the set such that \(e*a=a*e=a\) for every \(a\) neutral element (iv) for every \(a\) in the set there is another element \(a'\) in the set such that \(a*a'=a'*a=e\) inverse element
itz make sense dear
good
