Dear All
This is my confusing problem:
sage: m=31
sage: if m%3==0:
....: print m/3
....: elif m%3==1:
....: print (m-1)/3
....:
File "<ipython-input-2-ec9f38b42615>", line 3
elif m%Integer(3)==Integer(1):
^
SyntaxError: invalid syntax
sage:
I do not copy-paste the code. I have ubuntu14.04 and my sage version is 6.5.
