1: (A) Write True (T) in front of the true statement and false (F) in front the false atement: 1. Every subset of a ring R is also a ring. 2. The elements 1 and 3 are nilpotent in the ring (Z9, +9,9). 3. (R, +,.) is a Boolean ring. 4. (Z, +..) is a field. 5. Any ring must be commutative. 6. Every ring is a group. 7. In (Z5, +5,-5), the only zero divisor element is 0.
