Set the book 3-dimensional space.
In[2]:=

Out[4]=
{True,False,True,False,True,False,True}
Multigraded expressions give True only if all the element grades are even.

Out[5]=

α

α
{0,1,2,6}
Out[5]=
{True,False,False}
The raw grade of 0 is neither even nor odd.
In[6]:=

You can also use new symbols as long as you assert their grades, or you can override the grades of currently declared symbols.

The expression can contain powers (including reciprocals) of scalars. The quantity in brackets is multigraded and reduced to even grade by the interior product.
