Roster Form

In this, all the elements of a set are listed, the elements are being separated by commas and are enclosed within braces { }.

(1) Roster Form - Whole Numbers

• W = {0, 1, 2, 3, 4, 5, …}

(2) Roster Form -Integers

• Z = { …, −3, −2, −1, 0, 1, 2, 3, … }

(3) Roster Form - Rational Numbers

• It is a number that can be express as the ratio of two integers.

• No common roster form is there for rational numbers.

(4) Roster Form - Real Numbers

• It is an uncountable infinite set.

• The set is dense everywhere which makes it impossible for us to obtain a viable roster notation.
