Thanks for your answer! What exactly does "the same representation" mean in this situation? Neither english or math Wink is my native language..

Shouldn't at least this give the same result (true or 1 in both cases)?
simplify(2x-2==2(x-1)) results in true
simplify(2x-2==2x-2) results in 1

Any idea why quorem gives a different result inside/outside a program (and how to make it work within a program)?
