Sorry but you cannot. You can change the decimal mark from dot to comma but you cannot have the calculator separate the digits between thousands (thousands separator).

Did you enter a dot as a separator for the thousands? If yes, this is the error. The calculator interprets all digits following the dot as fractions of decimals.
So you enter 220.000 meaning 220 thousand, your calculator gets it as 220 comma 0, and thats where your three zeros go...

To make it right, enter your numbers as 220000 - 100000 and you'll get 120000 as result.

### Hi there. I'm using Casio FX-570ES scientific calculator. I would be glad if you could guide me as to how to obtain derivative of a polynomial expression e.g. y=12(x^2+6)^5

Here is an example. Instead of SIN(X) insert your polynomials.

The syntax of the command is where function is the expression you are differentiating
x is the value of variable x at which you are evaluating the derivative, and tol is the tolerance (the error) you are willing to tolerate in the result.

If you do not want to specify a tolerance just omit the last comma and tol.

To enter the command d/dx you use key sequence [SHIFT][Integral]
To enter the symbol x in the expression you press [ALPHA][ ) ]
To enter a comma you use [SHIFT] [ ) ]
To enter a power of 10 in the tolerance use [x10^X] key

Example : Calculate The key sequence is as follows
[SHIFT] [Integral] 3 [ALPHA] [ ) ] [X^2] [-] 5 [ALPHA] [ ) ] +2 [SHIFT] [ ) ] 2 [SHIFT] [ ) ] 1 [x10^X] [(-)] 12 ) [=]

DO NOT confuse [SHIFT] [ ) ] which enters the comma and [ALPHA] [ ) ] which enters the variable X. May 28, 2011 | Casio FX-115ES Scientific Calculator

### 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 ;
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).

### When I turn my 12c on it has a comma instead of a period.

Hello,
The comma is a three-digit separator that appears if number with many digits are displayed ( millions, billions). Since it is a financial calculator designed for money calculations, the comma can be helpful.
There is nothing in the manual that suggests that the three-digit separator can be removed. It can however be replaced by the point as in European Countries (especially France) where the decimal mark is the point and the three-digit separator the comma.

In short. I do not think you can get rid of the comma.

Hope you can learn to live with it.
