For A = {x|x is an integer greater than 7} and B = {x|x is an integer less than or equal to 12}, determine A∩B and A∪B.

A∩B =
{x|x is an integer greater than 7} and {x|x is an integer less than or equal to 12}=
{x|x is an integer greater than 7 and less than or equal to 12}


A∪B =
{x|x is an integer greater than 7} or {x|x is an integer less than or equal to 12}=
all integers
