To store a number into memory, press SHIFT [STO] and the name of the desired memory register. To recall a number from memory, press RCL and the name of the memory register.

Available memory registers are A, B, C, D, X, Y, and M. Those are on the fourth and fifth rows of the keyboard (the two rows immediately above the 7, 8, 9, DEL, AC row). You don't need to press SHIFT or ALPHA to access these names after the STO or RCL.

I don't think you can change the pi value on your calculator. However, what you can do is store 3.14 in the memory and instead of using the pi key, recall the number from the memory key.

How to use the various memory keys is outlined in the manual.

Good luck,

Paul

You can't. It can only convert integral numbers to binary base, but not fractions.

Press MODE 5 to bring up the equation types. Press 3 for the quadratic. Enter the three coefficients. Press = to see the first root. If the display shows x1 then press down to see the other other root. If the display only shows x then that's a double root. Given the two roots x1 and x2, the factors of the quadratic are (x-x1) and (x-x2).

To store a number in a register, press SHIFT [STO] and then one of [A], [B], [C], [D], [X], or [Y] naming the register. To recall a number from a register, press RCL and then the name of the register.

There's also a register M. You can add to the value in M by pressing M+, subtract from the value by pressing SHIFT [M-], and recall from M by pressing ALPHA [M]. The key is just above the AC key.

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.

You have set the calculator to a fixed number of decimal places.

To reset calculator, easiest way is just to go back to the defaults - SHIFT, 9, (CLR), 3, (All), =, (Yes)

This will clear anything you have put in memory

The memory locations are A,B,C,D, X, Y, M. Their markings (on the body of the calculator) are of the same color as the [ALPHA] key. The markings are on the right of the key

when you press the keypad the calculator scanline translate and encode this function to digital formula(1&0)which the brain can understand(microprocessor)and this digital formula stored in a store called register which can easily called out to go to display where you can see it.
