I'm new to sage so sorry if this is a stupid question.

When I try to compute the norm of a complex number Sage doesn't evaluate it:

abs(sqrt(3) + I)

gives the exact same thing ( instead of sqrt(10) ):

abs(sqrt(3) + I)

What am I doing wrong

You can further simplify as follows:

sage: abs(sqrt(3) + I).full_simplify()

Or use the norm function:

sage: sqrt(norm(sqrt(3) + I))
