Even more amazing is how its easy-to-use STATISTICS menu crunches data. It is so much fun that I perform statistical analyses of almost any data I come across. This of course means that I can explain better the meanings of these analyses.
As long no one has found a way to look at all the memory externally, we cannot really be sure if all memory is cleared.calculation with percent +/- change sign (direct entry of negative numbers) RV exchange registers (X-Y) F floating-point notation Fix fixed-point notation: the listed decimals can be chosen (0-9) Sci scientific (exponential) notation Eng engineering notation a b/ c allows entry and display of fractions Sqr square root x 2 square pi value of pi (3.1415..) can be recalled 1/x reciprocal trig trigonometrical functions (sin, cos, tan and inverses: arcsin, arccos, arctan) hyp hyperbolic functions (sinh, cosh, tanh and inverses: ar sinh, ar cosh, ar tanh) DMS-DD conversion of decimal and sexagesimal numbers log exponential and logarithmical functions (10- and e-base) y x raising to power SD one variable statistics: calculating mean and standard deviation nCr probability calculations P-R converting coordinates between rectangular and polar systems n! factorial So anyways I got a Casio fx-82MS 2nd edition and a 100MS. Unfortunately these are the ones which are all patched up. I came across this situation recently and ended up with a screen which I guess needed a secret code to access. Maybe these are only for the Devs.
This occurs because the teachers and the students don't have any knowledgment about calculators, for example, a fx-991ES plus or an used graphing calculator are cheap also(I got my fx-9750G for 3€ used), and have many functions more. If you have a Casio fx-82SUPER that is no longer working, you can first try replacing the 2xAA batteries. If that doesn't solve the problem, then you can consider replacing the calculator with a modern equivalent.On pressing these keys it ended up to a screen displaying 8888888888 and no keys work here except Shift and [on] Same for me. Even removing the battery doesn't seem to clear the memory completely, I once left the calculator without a battery for a whole day so all capacitors are drained as well, and I still got mixed results.
Yo PPL, it's been 4 months from the last reply and I hope y'all safe and sound. I really thank this team for its Intel.
