Creative Students

A colleague of mine told me that students wrote something at the notice board.
She asked me to have a look at it.
This is what they wrote.

******************

Study = Not Fail -------------- (1)
Not Study = Fail -------------- (2)

(1) + (2) : Study + Not Study = Fail + Not Fail
Study ( 1 + Not ) = Fail ( 1 + Not )
Study = Fail

******************

It is quite true.
Indeed, it is very logic.
But I think I can write a better one.

******************

Study = Pass ----------------- (1)
Not Study = Not Pass -------- (2)
(1) + (2) : Study + Not Study = Pass + Not Pass
Study ( 1 + Not ) = Pass ( 1 + Not)
Study = Pass
