Question
Good morning sir

Sir what is meaning of sets in mathematics.

Please expalin clealy as much as possible

Thanks

Hi Apsara,

A set is a collection of objects of the same type.  I know that sounds vague, but that gives sets flexibility for use in many areas of mathematics.

We can have sets of numbers: {4, 8, 9}
We can have sets of variables: {x, y}
We can have sets of Cartesian coordinates: {(1,1) , (2,4) , (-1,0)}
We can have an empty set: {}

Sets can be infinitely large: {natural numbers}
We can also make sets with strange descriptions: {numbers containing digits 6 and 9}

I hope this helps,
Azeem
