A={-1,0,1,2,3},B={{-1,0,1,2,3}.求A交与B,A并于BA={-1,0,1,2,3},B={{-1,0,1,2,3}.求A交与B,A并于BA={-1,0,1,2,3},B={

A={-1,0,1,2,3},B={{-1,0,1,2,3}.求A交与B,A并于B
A={-1,0,1,2,3},B={{-1,0,1,2,3}.求A交与B,A并于B

A={-1,0,1,2,3},B={{-1,0,1,2,3}.求A交与B,A并于B
交集即求公共元素,并集即将所有的元素合并
A={-1,0,1,2,3},B={{-1,0,1,2,3}}.(应该少个符号)
A交与B=∅,
A并于B={-1,0,1,2,3,{-1,0,1,2,3}}
