Hello,
There is a function to calculate them for you.

In CAS, or Algebra or Tutor Modes, use the x! option
In Run-Math, press [OPTN][F6] to pan right, then [F1] to access the (PROB) menu then enter option number corresponding to x!
The way it works is as follows
number ! [EXE].
Due to memory limitations, you can calculate factorials of numbers up to 69.

Hope it helps.

The Gamma function reduces to the factorial function if the argument is a positive integer. For this case see the screen capture.

For the true Gamma function with real argument, you might want to generate a table of values by using the general definition as an integral

This is taken from Wolfram Mathematica site
Gamma Function from Wolfram MathWorld
where you can find other expressions you might want to play with.

How do I set up my Casio fx-115ES to perform algebra?


This calculator cannot manipulate letter symbols, so it cannot do algebra. It can only use numbers whose values are known to it: either those on display, or those stored in variables A to E or F , X, Y, and M.

How can i solve derivative for the ex? Ex: f(x) = (x^2+3x)^3 (easy one, want to know how to get it on the calculator without defining a value for X) Cheers


The calculator can calculate numerical values of derivatives of functions (at a given point). It does not have a Computer Algebra System so what you want to do cannot be done. You should look for a Casio calculator with a CAS, such as the ClassPad, the FX_Algebra 2 or the FX 9860G. Sorry.

How we can multiply two algebraic equation in 991 ES CASIO calculators


The Calculator does not have a Computer Algebra System (CAS), and cannot perform algebraic operations with variables. However if you enter some expression with variables, it can solve for one unknown after it prompts you for the values of the others

3x-2x


In algebra x represents something. It is a place holder for some value. Now let that value be the word orange or some other word you prefer.
Read out loud the mathematical phrase :3 oranges minus 2 oranges
Complete the sentence as you used to do in grade school: 3 oranges take away 2 ( minus) 2 oranges leaves 1 orange.
Translate that sentence into mathematics : 3 oranges - 2 oranges = 1 orange.
Since this operation is true for oranges, pears, pencils, what have you, use the symbol x as a place holder for oranges, pears, pencils, what have you and write the universal truth which is
3x-2x=1x.
Make it more sophisticated by remembering that if a factor before a variable has value 1, you can just drop it. That leaves 3x=2x=x.
By the way, your calculator is just a scientific calculator without a Computer Algebra System and cannot make sense of symbols that have no values. So it cannot do it.

How can i do algebra and keep the pronumerals and not use the inputted number? I am using the latest casio, it is a scientific calculator (not sure which model)


It is always risky to try to answer a question about a calculator of an undisclosed model.
To be able to symbolic algebra (with variables), one needs a calculator with CAS (or Computer Algebra System). These types of calculators are special graphing calculators. ( Not all graphing calculators have a CAS.)

To get back to your question: No, you cannot do algebra with a mere scientific calculator even a recent one. All you can do is define an equation with variables A,B,C,D, Y and X and press the Solve button if it exists. The calculator will ask: Solve for X?. If you say yes, you will be prompted for the values of all letters (A,B,C,D, Y) in your equation and the calculator will search for the value of X, that makes the left side of your equation equal to the right side.

It will display the X-value and the difference L-R.

Can i calculate calculus using fx-991ms


If you want to get an answer like 1/2X for d/dx(X^2), you will have to purchase a CAS calculator like Casio's Algebra FX-2 or Classpad. TI series calculators also have CAS.
However, you can calculate the numerical values of derivatives and integrals only.
To calculate the value of a proper integral:

  1. Press the 'ON' key;
  2. Press the Integral key b8325f5.jpg;
  3. Enter your expression (example X^2+X-3 etc);
  4. Press the 'comma' key after your expression;
  5. Input the first limit after comma, input comma again after first limit;
  6. Close brackets;
  7. Press the equals key, display may return after a while with the answer.
for eg to calculate xdx from 0 to 2, input as follows:

dx(X,0,2)

To calculate derivative at a point:

  1. Press Shift and then the integration key.
  2. Enter your function;
  3. Input comma;
  4. input the point at which you want to evaluate the derivative;
  5. Close bracket and press enter.
Example, to calculate d/dx X^2 at 3 input:

SHIFT+dx key X^2,3)

Display looks like this: d/dx(X^2,3).
