Hello,
I have a problem with my CASIO GRAPH 25 calculator. Whenever I press the "7" key, the screen shows "1"; whenever I press the "8" key, the screen shows "2"; whenever I press the "9" key, the screen shows "3".
And when I press the "DEL" key, the screen shows "+".
Thank you very much for your help!!!
