Hi Sage-Support:
I recently updated my sage to the recent version available from sage
-update. And, I am faced with this problem:
sage: var('x')
x
sage: simplify(x+1-x)
---------------------------------------------------------------------------
RuntimeError Traceback (most recent call last)

I am on a OS X 10.9.2 box. Can someone please tell me how to fix this
problem?
With Sincere Regards,
Kannappan.
