MODEL- EL-520WBBK         VENDOR- SHARP ELECTRONICS
    
FEATURES- Advanced Scientific Calculator- Black
       The EL-520WBBK performs over 419 advanced scientific functions and 
        utilizes a 2-line display and Multi-Line Playback to make 
        scientific equations easier for students to solve. It is ideal for 
        students studying general math, algebra, geometry, trigonometry, 
        and calculus. In addition, it can be used for statistics, biology, 
        chemistry, and physics.
* Direct Algebraic Logic 
   Allows students to enter the elements of an expression in the exact 
   order they appear in the textbook. 
* Extra Large Display 
   12 digit, 2 line display - 1 line equation and 1 line numeric.
* Multi-Line "Playback" 
   After getting an answer the user may then "playback" the expressions and 
   substitute new numeric values. 
* Additional Features 
   Includes differential and integral calculus functions, 419 functions, 
   and hard case.
