PHP If statements. Stacked parentheses explained?

Hi,

Can someone please explain the proper use of stacked parentheses like so:

if( $x == 3 && $y == 8 ){
    echo 'hi';
}

Against:

if( ( $x == 3 ) && ( $y == 8 ) ){
    echo 'hi';
}

What would be the significance of the added parentheses?

Thank you

Just like math class -- to distinguish which comparisons are executed first.
