For example, the collection of the an initial 20 natural numbers divisible by 5 deserve to be represented in roster notation like: A = 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100.

Given below are 3 Venn diagrams representing three various sets. Allow us stand for them in roster form step-wise.

Set A consists of only a single element thus the elements in roster kind can be stood for with curly brackets ⇒ A = 10.Set B contains multiple facets hence the facets can be stood for in roster kind as B = 3, 7, 4, 5, 8, 11The facets of collection C deserve to be stood for in roster kind as C = x, y, z

Limitations of Roster Notation


One the the constraints of roster notation is that we cannot represent a large number that data in roster form. For example, if we desire to stand for the an initial 100 or 200 herbal numbers in a set B then it is tough for united state to stand for this lot data in a solitary row. This limitation can be get over by representing data through the aid of a dotted line. Take a set of the very first 100 confident odd numbers and also represent utilizing roster notation.

B = 1, 3, 5, 7, ....., 199

The dotted line mirrors that the numbers are component of set B however not composed in roster notation. When we represent large numbers of aspects in a set using roster form we typically write the first couple of elements and also the critical element and also we separate these elements with a comma. Let's take a collection of every the English alphabets, it have the right to be represented in roster kind as:

C = a, b, c, d, ......., z

If any set has one infinite number of elements prefer the set of all the also positive integers, it can be stood for in roster type like:

D = 2, 4, 6, 8, ......

We just can denote the rest of the numbers through a dotted line since there is no finish to positive even numbers, we have to keep it choose this.
