Default Maths Tutorials -I

What has prompted me to submit this is the minimal response to Maths Quiz-II.


A Group consists of only two things:

1) A Set and 2) an operation.

The operation can be plain addition,plain multiplication,Matrix addition or multiplication, or any other operation to be explicitly specified.

Now the following conditions must be fulfilled:

1) An operation on a member of the set must yield a member of the set
(This property is called CLOSURE )
2) Must have ASSOCIATIVE property
3) Must have a Neutral or IDENTITY element

4)Existence of INVERSE
Collectively this can be remembered by acronym: CAIN

Populaar example: Integers with operation: addition

Will be only too happy to elucidate further.
