Question about Texas Instruments TI-84 Plus Calculator
Pressing each key in the 4th column gives a read-out of 9. If the 2nd key is held, pressing each key in the 4th column will give a read-out of w. Why is this happening?
Have you ever dropped it? If so, there may be something wrong inside it and you may have to open it up and see. I am not much of a technition on the inside of the calculators, but check to see if any thing is busted or if there are any "loose wires". If not I suggest that you ask a professional.
