### x=var('x') - getting TypeError: cannot perform reduce with flexible type

I just installed Sage 5.12 under Mac OSX 10.8. I started the notebook and then proceeded to work throughout the "Getting started" document. In Chapter One, the first page there is an example of Symbolic programming. It starts with:

x=var('x')

When I evaluate this I get the following error:

Traceback (most recent call last): File "<stdin>", line 1, in <module> File "_sage_input_16.py", line 10, in <module> exec compile(u'open("___code___.py","w").write("# -- coding: utf-8 --\n" + _support_.preparse_worksheet_cell(base64.b64decode("eD12YXIoJ3gnKQ=="),globals())+"\n"); execfile(os.path.abspath("___code___.py")) File "", line 1, in <module>

File "/private/var/folders/k_/vvbn4jxs6jx2z21s7xdj088c0000gq/T/tmpZ3Z0gy/___code___.py", line 2, in <module> exec compile(u"x=var('x')" + '\n', '', 'single') File "", line 1, in <module>

DOES ANYONE KNOW WHAT IS WRONG WITH THIS. It is there own introductory example, and it is not working.

The error appears to be emanating from it won internal version of Python.

Thanks an advance for any help.

It is there Sage's own introductory example, and it is not working. working! It is the fist thing I tried, so it does note give one confidence with the system.

If I try this from the SAGE command line (as opposed to the notebook) it appears to work. Am I doing something fundamentally wrong by using the notebook for this?
