    @BenjaLim: Apparently there was a period some time (more than a year) ago when the site was overwhelmed with variants of this question. Seeing it again must have been a traumatic experience for someone.2012-06-28

    The Casio fx-570MS to the left is a model from 2005, whereas Casio fx-50FH was introduced in 2008, so I would go with the newer calculator on the right. Which, incidentally, has the right answer.2012-06-28
