    When programming with the HP48G series, you have a choice.  Suppose for
    example, you want to multiply the sine of latitude times the sine of
    declination.  You can either use RPN:
    
            Lat
            SIN
            Dec
            SIN
            *
    
    or algebraic notation enclosed in single quotes:
    
            'SIN(Lat) * SIN(Dec)'
    
    It gives you the best of both worlds.
