SOURCE: mode change
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.
SOURCE: Casio fx-7400G PLUS cubic solver?
Hi,
First let us repair the terminology.
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.
