Hello,

Just so that we know what we are talking about. The natural display is the display mode in which fractions appear on two lines, radicals appear as radicals, log can be calculated in any base, etc. If that is what you understand by Natural Display, we are in agreement.

To set this mode, you turn calculator ON and press [SHIFT][MODE] (setup). The option is called MathIO, and it has the number 1.

Thus [SHIFT][MODE][1:MathIO].

Hope it helps.

Hi,

First let us repair the terminology.

- You can evaluate any expression (find the value of any expression for a particular value of its variable).Store a value in the variable, say X. Key in the expression and press [EXE].
- You can consider your expression(should not contain a relational operator such as =, greater than, less than, greater than or equal to, less than or equal to) to be a function Y1(x) = expression and graph it, or generate a table for it. You will have several values of the function calculated at various points.
- You can set your expression equal to 0 and find the particular value(s) of the variable (the unknown) that make the equality TRUE. That is called solving an equation.

Hope it helps.

Thank you for using FixYa and for rating this solution.

SOURCE: As the Casio FX-991es Plus got a modular function

It's a bit convoluted, and it only works for integers, but here's one way. Press MODE 4 to switch to BASE-N (integer) mode. If the screen doesn't read "Dec" then press the x^2 key. Now, to calculate a mod b, calculate a-a/b*b. No shortcuts, no rearranging. That's a minus a divided by b times b. You have to enter both numbers twice, but you will get the modulus.

Press MODE 1 to return to your previously scheduled calculations.

Use nCr (the shifted function of the divide key). For example, to find the number of combinations of five things taken three at a time, press 5 SHIFT nCr 3 = and see 10.

This is a good scientific calculator that can do a lot, but things in the realm of a CAS (Computer Algebra System) are beyond its capabilities.

You should try to explore the calculator to find its capabilities. You can also read the manual. Everything is in it.

Sorry, It is not possible to solve equations on the Casio FX-82 ms. Try the Casio FX-115 ES/ FX-115 ES Plus, FX-991ES/ FX-881 ES Plus C.

The FX-991ES Plus barely handles simple operations on matrices of dimensions up to 3X3. It cannot find eigenvalues or eigenvectors.

You cannot. The calculator does not have a Computer Algebra System or CAS. If you are trying to calculate an integral over an infine interval, you must try some high values to simulate infinity and find a value after which the value of the integral stops changing .

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.

Hi,

If you cannot find it, buy an FX-991ES. It is solar-powerd and it has the natural text-book display, which is a novelty in calculators.

I know that Staples carry the FX-991ES.

Hope it helps.
