## anonymous one year ago Can someone explain to me what "null set's" are? I'm a little confused on this subject.

{ }

In mathematical sets, the null set, also called the empty set, is the set that does not contain anything. It is symbolized or { }. There is only one null set. This is because there is logically only one way that a set can contain nothing.

A null set is an answer that doesn't contain anything. And looks like this { } or a 0 with a slash on it

There is no good mathematical definition for a set, so we just say that a set is the thing you think it is. The empty set (or the null set) is the set that contains nothing as everyone here said. $$\emptyset = \{\}$$ Here is one way we could use such a thing. What is the set of real number solutions to the following equation $$x^2=-3$$. This set would be empty because there is no solution to the above equation.

Null sets are sets of measure zero. the empty set is one example.
