SOURCE: How I can memorize my

Sorry, but you cannot.
You can type in a formula that involves the memory variables X,Y, A, B,C,D, E, =, . Such a formula is meant to be evaluated to get a solution (X by default). Once you type the formula you press the Shifted function SOLVE and you will be prompted for the constants, for Y etc. when you press the EXE/= key you get the value of X.
If you turn off the calculator or change the calculation MODE, it is wiped out of memory.

To make a long story short, you cannot STORE formulas in the calculator. Better try to memorize them (commit then to YOUR OWN memory).

Casio fx-991es plus upside down display


I would take it apart and see if they installed the display upside down. I wouldn't think the wires would be long enough to do this, but maybe that is the way it is laid out.

Good luck.

Can I convert Decimal Degrees to Degrees, Minutes, Seconds on my casio fx-991 ES?


Yes. Pressing the DMS key (two keys above the 8 key) when a result is displayed toggles the result between decimal degrees and degrees-minutes-seconds.

For example, to convert 3.5 degrees, press 3 . 5 = and you'll see 3.5. Now press DMS and you'll see 3 degrees 30 minutes 0 seconds.
