Determine whether the following mathematical systems are groups or not. If it's a group, explain why all four group conditions (closure, identity, inverses, associativity) are satisfied. Also, specify if the group is Abelian (commutative). If it's not a group, show at least one of the four group conditions that is not satisfied. a) The set of even whole numbers under addition. (Remember that the number 0 is even since it is a multiple of 2:0 = 2 x 0)
