SOURCE: mode change

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.

SOURCE: Casio fx-7400G PLUS cubic solver?

First let us repair the terminology.

  1. 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].
  2. 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.
  3. 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.
I am not sure that it has a solver (solving an equation or an inequation) but you can always draw your expression as a function and explore the graph (SKTCH) to locate the roots (or zeros) of the functions (the values of the variable where the function equals zero.) That is called solving graphically.

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.

How i can get infinity symbol in casio fx-991es plus calculator

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 .

Casio fx-991es plus upside down display

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.

I have to buy Casio FX-991W Plus. No one has it. I checked eBay and the Casio web-site. I need that one. where can I get it from?

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.
