\ \hline 1 & 1 & 0 \\ \hline \end{array} \] Answers the questions: (i) Name the identity element i... belian? **Solutions**\\ (i) From the given table we have $0+0=0$ and $0+1=1$. This show that $0$ is ... )=(-a)+a=0$. Thus inverse of $a$ is $-a$. Hence, we conclude that set of integers form groups with re... roup. For $A\in P(S)$ where A is a subset of $S$ we have $S\in P(S)$ such that $A\cap S=S\cap A=A$.
