I am writing a .tex file that require me to draw some trees but I keep getting errors.
I'm using the qtree package and I am trying to use the following line
\Tree [.+ 5 [.+[.* 5 2] [.* 2 4]]]
but when I compile I get this error:
! Paragraph ended before \doanode was complete.
<to be read again>
What am I doing wrong?
