Question about Casio FX991ES Scientific Calculator
I change the mode to comp but it changing automatically to cmplx
Try a reset SHIFT 9 (CLR) and reset 3:All
Also if Mode:1: COMP gives Complex, maybe MODE:2:CMPLX will give you the usual COMP mode. (wires may be crossed). I have a calculator that has two keys inverted. I made a note of it and keep it taped inside the sliding cover.

I get an answer of one.
To clear your calculator back to default, to the following:
CLR (the button 9)
3 (select option 3 = All
= (the equal button)
AC (the red AC button)
Your calculator is now reset to factory settings
Now try your calculation.
