The 2nd to last row on the number pad on the calculator displays the units below it. When I press number “1” it shows “0” When I press “2” it shows “ . ” when I press “3” it shows EXP When I press “-” it press “EXE” (enter)
whatever I press on the 2nd to the last row displays the units that are in the last row. Please help me thanks.
I fixed it boys, I opened it up and blew under the circuit board and the rubber piece
