and my bro go NUS and having hell wif his questions; serves him right lol... see ah:
A binary operation * on a set S is an assignment which assigns to every ordered pair (x,y) of elements x,y in S exactly one element in S. A set of objects together with a binary operation * on S is called an operational system. For example , the set of whole numbers is an operational system with binary operation +.
An element g in S is called an identity of (S,*) if for all x in S,
g* x = x = x * g.
Using the above information , answer the following questions.
Consider the following operational system with binary operation & with the following multiplication table.
& P Q R
P P Q R
Q Q Q Q
R R Q Q
(a) find P & Q, P & R, P & P
(b) what is the identity of this operational system. Give a reason for your answer.

WHAT THE FISH?! GAY QUESTIONS! lol if i was given this type of questions in SEC 1 i would probably go kill myself or something.. lol go do compo liao bb
