k in destroy number 150 it shows: !x!>a or !x!> -a for a greater than sign (by the way ! means absolute value)
and kaplan has this x>a or x< -a for the greater than sign---its in the blue book on page 617


which is correct


i c wat ur sayin doc...my bad, kaplan never had those absolute values, now which one is correct? so in other words, which would u use for a problem like !3x-6!>9

The bold would mean a positive number is less than a negative one.
