You may need to show context, but it appears that this table DEFINES the operation *; it is not just ordinary multiplication. So each table just tells you the facts listed below the table. You can fill in a table any way you want to, and it will define an operation (which may or may not be an interesting or useful operation!).Can someone explain to me, why is a*a= e?
It is a Cayley's table. e is defined as an identity element/neutral element. By multiplication is e:=1
If e=1, then why is a*a=e?
I am confused because if I want to get e, I have to do this: a*1/a=e
In the next picture is a*a=b why?
