Is it?

   1 == 0   (false)
   1*0 == 0*0   multiply both sides
   0 == 0   (true)

I don't see it as a problem, as "false implies true" is true.

The only problem is if sage takes something true and turns it into something false, which is the case if "101 > 100" is turned into "-101 > -100" by multiplication by -1 (the case which started the thread).

I stand by what I said: equality isn't a problem.
