Kunen and Miller used this method to construct a mathematical universe that satisfies add (𝒩) < add (ℳ). In this model, more meager than null sets are required to form a non-negligible set.

We want sets to be extremely flexible objects, capable of taking on many roles in different parts of mathematics. A finite collection of variables, like {x, y, z}, should be a set.

In this lesson, students learn to find the fraction of a set. In this lesson, Ms. Brewer will teach 3rd grade math students to find the fraction of a set. / Carrie Brewer, East Saint Louis School ...

Sets There is good reason to have a fairly open-ended definition like this. We want sets to be extremely flexible objects, capable of taking on many roles in different parts of mathematics. A ...
