Hello,
If by calculus problem you mean derivatives of functions, integrals, extrema and such things, I am sorry to inform you that neither the Casio FX-300MS, nor the FX-991MS can handle them. The newer Casio calculator FX-991ES is capable of performing numerical differentiations and integrations. There also graphing calculators by Casio FX-9750G, FX-9860G as well as by Texas Instruments (TI 83 PLUS/TI84PLUS) that are reasonably performant in that area.

Hope it helps.

Hi,
Turn calculator ON. Press [SHIFT] [9] (CLR) and select
  1. Setup,
  2. Memory, and
  3. All.
  4. Then press [=] to execute the reset.
Note: The choices of reset options are those available for the FX-991ES. But the procedure is similar.

Hope it helps.
Thank you for using FixYa and for rating this solution.

Seems to be a common problem on this otherwise great calculator that helped me through both high school and university. I've had mine for nearly 20 years and this problem showed up a few years ago. But I remember classmates reported the same problem when it was almost new.

If replacing batteries isn't helping, the problem is most likely caused by oxidation on the springs connecting the battery holder to the main PCB. The solution is as follows:

1. Remove the metal back cover (2 screws)
2. Remove the plastic back lid by removing the black screws (leave the batteries mounted) and CAREFULLY slide the back lid to the lower end (where the EXE button is located). Do not lift while sliding until the lid easily comes off.
3. On the back side of the plastic lid, very carefully bend the the two metal connectors ~1 mm on both batteryholders to increase their tension.
4. Clean the connecting pads on the PCB and the metal springs with de-oxidizer solvent.
5. Re-assemble and your 4500P calculator should be good as new.

Hello,
Here is a link to Casio New Zealand. Enter the model number for your calculator (with and wihout the hyphen, I don't remember which) and download a bilingual manual. The quality of the copy is to say the least ... Well, why not let you discover it for yourself.

Bye.
