A MATHEMATICAL WONDER!This item is LIKE NEW.
FROM THE MANUFACTURER:Seven wooden strips with random numbers written on both sides of the strips are displayed. A volunteer is asked to place any five strips in any order into a wooden frame thus forming 5 five-digit numbers. You then instantly reveal the total of these five five-digit numbers, faster than a computer.Over hundred thousand combinations of numbers are possible with the seven strips. You can accurately reveal the total of each and every combination, faster than a computer can add them.The strips and the frame are made of wood and lacquered to a high finish. The frame measures 5.5" x 6.5" . This is a very easy to do trick that will set your reputation as a Mathematical Genius.
The frame and strips are like new. Please look at the photo.
