Casio FX-9750GII

Casio FX-9750GII (Graph 35+) also belongs to the same series and can be flashed into Graph 75+. 188.163.50.187 (talk) 16:09, 16 August 2018 (UTC)[reply]

Feel free to edit the article yourself to include information about this model. Deryck C. 17:00, 16 August 2018 (UTC)[reply]

fx-9860GIII vs. fx-9750GIII

I would like to update this page, so I just spent nearly an hour searching to find out what the exact difference between these two models is. Alas, Google keeps "helpfully" assuming that "GIII" is a typo and gives me pages about "GII" models. :( does anyone have a source for the differences? --Guy Macon (talk) 15:17, 14 October 2020 (UTC)[reply]

I looked through the manual and so far I found three differences.

First the fx-9860GIII has what they call "math" mode. This allows you to input things the way you see them on paper: a 1 over a 2 for 1./2, etc. But it uses the same format for the output. so 1/2 + 1/4 = 3/4. That's what grade school students like, because the teacher asked them to convert fractions. But when an engineer types, say, Pi over 16 he wants to see something like 0.196349540849362. not the same Pi symbol over the number 16 that he typed in. The fx-9750GIII also has what they call a "Mth/Mix" mode that gives a numeric result.

Second, the fx-9750GIII but not the fx-9860GIII allows you to set the priority of implict division to be that same as explicit division. See [1][2][3]

Third, the fx-9860GIII has Examination mode for International Baccalaureate only, while the fx-9750GIII has Examination mode for International Baccalaureate and for Texas (Texas requires disabling the inequality graph command)

So basically you can configure a fx-9750GIII to act like a fx-9860GIII, but not the other way around. --Guy Macon (talk) 23:28, 14 October 2020 (UTC)[reply]
