Why don't the buttons on my calculator work?

Yes, thank you so much! Resetting my calculator corrected the problem.

Everything about my calculator works perfectly except there are no numbers on the keypad. I have to try to remember where the numbers are at when I am typing because there is nothing there. What is wrong with my calculator?

My calculator can’t on..can you tell me the factor why it can’t on?

so my calculator won’t work and it just shows on the very top corner error and the number I type in barley shows
