Sorry you cannot.store many numbers. Memory locations are at A, B, C, D, E, F in addition to X and Y. But why would you want to store the squares since the calculator can calculate them readily.

To perform other functions (more than 400) do read the manual.

Hi,

A 6ya expert can help you resolve that issue over the phone in a minute or two.

Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

The service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

Good luck!

1ST YOUR GONNA NEED BUFFERS:

All pH meters require calibration standards to ensure that the readings are traceable to a standard. Always choose a pH 7 buffer plus at least one other pH value close to your expected measurement range. Using solutions of known pH value allow you to adjust the system to read accurate measurements. Calibration should be performed before each reading or each set of readings.

After that this model has auto buffer select and it will tell You what buffer you put it in , also will ask if you want to correct it as well

The FX-991ES Plus barely handles simple operations on matrices of dimensions up to 3X3. It cannot find eigenvalues or eigenvectors.

The calculator can calculate numerical values of derivatives and integrals but does not calculate limits of functions. Sorry

In table Mode you can enter the formula for a function and generate a table of values. For a 991ES Plus you can enter two functions. However if you change MODE everything will be erased.

In EQN (equation) there is a certain number of built in formula types you can choose. You will be asked for the coefficients which will be used to solve the equation selected. However if you change MODE your lose what you entered.**So basically you cannot save formulas to use as a memory aid **(if that is what your intention is.) Sorry.

FFF code - Control error, failed EEPROM

The main control operates a series of software commands, which control the various features and functions of the oven. Each function or operation has a numerical value assigned to it. The numerical values can be added up - this is called the check sum operation. Every time the system is powered up and after each clean cycle the system performs a check sum and compares the value to the value programmed into the software (stored in memory).

An EEPROM check sum error or FFF code occurs when the values differ. If this happens, replace the oven control board (also called clock or ERC).

Replace the oven control board (also called clock or ERC).

Hope this helps.

You can store values in the memory locations A,B,C,D,X and Y. To access these variables, you must precede the key by pressing [ALPHA]. Thus to access Memory variable A press [ALPHA][(-)].

To store a number in memory A Press [SHIFT][RCL] (STO) . When you use the shifted key to store no need to press [ALPHA].

To recall the contents of memory A, just press [RCL] followed by [(-)]. No need to press [ALPHA]

Say you want to calculate 3 5 and assign value to memory A

3 5 [SHIFT][RCL] [(-)] A.

Similar sequences for B,C,D, X, and Y.

I am not sure about the Casio FX300ES but the FX-991ES does have a solver mode. On that calculator, to enter the = sign in an algebraic equation use the [ALPHA] key followed by a key on the top left of keypad ( Could be CALC).

I suggest you refer to the manual for the calculator for examples of use for the memory keys. Look in the separate Appendix too.

Hello,

This calculator can only perform NUMERICAL DEFINITE integrals. Which meansyou have to supply the numerical value of the lower limit and the numerical value of the upper limit. The result is a numerical value.

The calculator cannot perform symbolic calculus.

If the function is simple you find the integral in tables of integrals where you will see that INT(log(X)dx=x(log(x)+1). Some calculators that have a CAS (computer algebra system) can manipulate symbolic expression, but not theCasio FX-991ES.

You ask it the value of the integral of log(X) from X=1 to X=3 and it will give you 0.5627748004

Hope it helps
