You can also use one of the following tricks.
- you can make a cell python by typing
%python
in the first line of the cell.
- towards the top of every notebook worksheet,
there are four drop-dow
Can we not use + to add complex numbers?
sage: j = -1/2 + sqrt(3)/2*i
sage: a = -2*j*j
sage: b = -j/2
sage: print a.real(); print b.real(); print (a+b).real()
1
1/4

sage: K. = NumberField(x**
