Definition of Empty Set. An Empty Set is a set with no elements. It can be symbolized by {} or Ã¸. The solution set for an equation that has no solution is also called an empty set.It is also called a null set. A = {2, 6, 8} and B = {3, 5, 7}. Let C represent the intersection of the sets A and B. C = {}, a null set, because there is no element common between the two sets.
A set in math is a group of items. It can be a group of numbers, variables, or anything else you can think of. When two or more groups have an item or items in common, the subset of items they have in common is what we call the intersection of sets. For example, let's say we had two different sets of numbers.
