How To Write The Elements Of a Set?

Let’s see how can we write the elements of a set theory? In order to do so, we have two methods:

1. Set Builder Form

Under this method, we put elements in a statement form. For example; A={x|x is a natural number < 5}. This set is read as ‘A is a set for all x such that x is a natural number less than 5.

2. Rooster Form

Under this method, we write the actual elements of a set. Using the same example; A={1,2,3,4}. As you can observe, I wrote the actual elements which were the natural numbers less than 5.


Test Yourself

Why don’t you try writing a set of vowels of English alphabets in set builder form and rooster form. You can email me your answer on contact@LearnWithAnjali.com

To summarize, under set theory, we can represent a set either by writing the property or by representing it in a tabular form which is popularly known by the rooster method.
