Definition..a group G is a mathematical object .

Defined as a non empty set G with a binary operation (*) and satisfy below 4 properties

```
1) closure
a*b=c , a,b,c €G
2) associativity a+(b+c)=(a+b)+c
3)G have identity element e which is unique
such that
a*e=e*a=a
4) have inverse of each element such that
a*b=e for all a,b €G
```
