Rey Louie Camu says:

Hello sir, i have a problem with this calculator. it cannot shift solve another variable except for X.. while the lower version
fx-991ES plus can shift solve another variable.. for example i input the function 2x+2C=2y^2,C (comma C to shift solve for C) then it will ask the value for X and Y then will solve for C. but the 991EX classwiz cant do that. have you encountered this? thanks for answering

jason laverty says:

I need some advice please.
I have a very old casio fx570 which allows me to input values in micro, pico, nano etc for my electronics calculations. I know on any normal calculator I can put in say :5 exp -6 to get the value 0.000005, but my old casio allows me to input 5 shift 4 and hey presto 5u appears on the screen….Yes Im lazy , but when you are quickly trying to trouble shoot a circuit problem it makes a difference.
I need to replace it as some of the display is now going down and I was hoping you could advice me of a current model that will give me this functionality.

Athul Rag says:

is it possible to replace the solar panel of casio classwiz 991EX?
My calc solar panel accidently cracked and now it isn’t working//////////

Alan K says:

Hi – Me again.

Say if I wanted to calculate the probability to of P(Z<1.2) just using the calculator, how would I do that in Normal CD mode? Also for A-Level Stats is it right to be in CD mode or is PD mode the correct one?
