Is it possible it were still doing sum but don't have the juice to show it ? :-D Anyway, solar + battery is better than battery alone. My Casio FX-115MS had a dead battery, but still work under good light. The back is somehow stuck even with all 3 screws removed (glued stuck ?) Cannot replace battery without breaking the calculator ... FX-115MS also had some weird precedence, had FX-991EX fixed it ? Keys: 6 / 2 ( 1 + 2 ) ==> 1 ? Keys: SQRT 6 RCL Y ==> sqrt(6 * y) instead of sqrt(6) * y Keys: SIN ( 30 DEGREE ) SQR ==> 0 ? Above actually does sin(30 ^ 2) = sin(900) = sin(0) = 0 To do sin(30) ^ 2, had to do ( SIN 30 DEGREE ) SQR ==> 0.25 |
