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).

### I own a Casio Scientific calculator fx 910 I lost the operating manual can you e-mail or send me the book of instructions? Peter Brunett e-mail pete@rgengineering.com ph# 757-406-3091

I don't believe I have heard of the model FX910 you refer to. I suspect there is a typographical error: Could be 991. Any way, the FX-991 comes in several "species" and I can only give you the link to the page whence you can download the relevant manual.

Look under the "Scientific Calculators" heading. For each manual, read the whole title because one single manual may do for several calculators.
