Press the [MODE] button 3 times then 1 to enter EQN mode. Then press the right pointing arrow. You can select the degree of the polynomial (2 or 3) or press again the right pointing arrow to select the number of unknowns for simultaneous linear equations( 2 or 3).

The form of the equations are as follows.

On a fx-991MS? With many other models, including the fx-991ES, I'd say you have the calculator in binary mode but the 991MS doesn't have such a mode.

Your question (?) is not clear so I will not try to guess what you really mean.

Be it as it may, the Casio FX-9860G SD can solve a polynomial equation of degree 2 or 3 with REAL coefficients. If the complex MODE is set to REAL it will find the real roots. If the complex mode is set to** a+ib**, it will find the real and complex roots.

Apparently it will take coefficients that are real, and will give a Ma Error if any coefficient is complex.

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.
