Hi,

Sets can be defined as the well defined collection of objects. We can describe sets in two ways. These are listed below.

1) Tabular form : In this form, the set elements are simply written and separated by commas and closed within curly braces.

Ex. A = { 2,3,5,8,-1,0}

2) Set builder form : In this we imply some condition, so that we can generalize the set elements by seeing that condition only.

Ex. A = { x : x = 2n and n<= 5 }

Hope it helps.
