PHP short tags echo method (without the equal to)

Very simple:

So... That is working perfectly

<?=($A>9)?":)":":(";?>

Now... How can I say the same exact thing without = AND without echo ?

iow... I want to use that shortcut technique inside php code in between other php lines.

so this is NOT the correct syntax but just to get the idea more clearly...

<?

$A=50;

($A>9)?":)":":(";

?>
