Viết các tập hợp sau bằng cách liệt kê:
a) \(A = { \rm{ \{ x}} \,{ \rm{|}} \,{ \rm{x}} \in \mathbb{Z} \,{ \rm{;}} \, \, \, - 3 < x \le 3{ \rm{ \} }} \);
b) Tập hợp \(B \) gồm các số là số đối của 3; 1; 0; -2
A.a) \(A = {\rm{\{ }} - {\rm{2}}\,{\rm{;}}\, - 1\,;\,\,0\,;\,\,1\,;\,\,2\,;\,\,4{\rm{\} }}\).
b) \(A = {\rm{\{ }} - 3\,{\rm{;}}\, - 1\,;\,\,0\,;\,\,2{\rm{\} }}\).
B.a) \(A = {\rm{\{ }} - {\rm{2}}\,{\rm{;}}\, - 1\,;\,\,0\,;\,\,1\,;\,\,2\,;\,\,3{\rm{\} }}\).
