What do you mean by set builder method?

Set – builder notation is the mathematical notation for describing a set by stating all the properties that the elements in the set must satisfy. The set is written in this form: {variable ∣ condition1, condition2,}. The bar in the middle can be read as “such that”.

What is the example of set builder form?

A set – builder notation describes or defines the elements of a set instead of listing the elements. For example, the set { 1, 2, 3, 4, 5, 6, 7, 8, 9 } list the elements. The same set could be described as { x/x is a counting number less than 10 } in set – builder notation.
