I have a question about notation. Just let me write it out.

OpenStudy (anonymous):

\[3x^2 >= 0\] \[\forall x \] (three dots like a triangle upside down) x^2 is always positive. Sorry for the line spacing, it should all be on one line. Would this read: "3x^2 is more than or equal to 0 for all x because x^2 is more than or equal to zero" ?
