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.

To configure the calculator to do fractions, set the Input/Output mode to MathIO.
Press [SHIFT][MODE] to open (SetUp) then select [1:MathIO].
After you set it to MathIO, pressing the fraction key will display a fraction template where you can enter numerator and denominator as you would by hand (horizontal fraction bar). Also, the calculator will display results as fractions and radicals whenever possible.
To perform arithmetic operations on fractions use the regular operation keys (x, +, -, /). The calculator will perform the operations and display the results as fractions (whenever possible).

How do you turn frequency on when in the stats table mode on a casio fx-9750gii?

There is no such thing as turning the frequency on on the Casio calculators. Just enter your data in lists. Choose one List where you put the frequency information. When you want to GRAPH or perform CALCulations you have a TAB labeled SET corresponding to key F6:SET. When you press F6, a new screen open where you assign the list to the variables.
Here are a few screen captures to help you.


Press F2:CALC (or F1 Graph). The Tab SET appears at the bottom of screen


Press F6:SET
Higlight the line 1-Var Freq (or 2-Var Freq). The bottom of screen shows F1:1 and F2:LIST. If frequencies are not equal to 1, press F2:LIST to assign the frequency list. I entered 2.


List2 is now the frequency list.

Press EXE to perform stats.


See that n=19.

How to get mod on it

If you are thinkink of the modulo function, usually shortened to mod(, I am sorry to say it but that function does not exist on the calculator.
However, there is MODE button that one uses to set the operation mode of the calculator.
You have three principal mode setting
COMP: the general computational mode
SD: a statistics mode to calculate Standard Deviations
REG: to perform REGression analyses on statitical data.

Once you have chosen the preferred calculator mode (COMP, SD, or REG) other choices (dependent on the main calculator mode) will be available.

[2nd][MEM][7:reset][1:All ram][2:Reset] Memory cleared displays on screen. Some games remain stuck in memory, preventing you calculator from performing correctly.
No you are not dumb. You just have to learn how to get youself out of an unpleasant situation. Truth is a set of corrected errors.

Hope it helps.

The [MODE] key can be used to select the modes described below.
Important! The following is a general explanation of Scientific Calculator modes. Note that your calculator may not include all of the modes described here.
1) Calculation Modes
Before performing a calculation, you first need to select the appropriate calculation mode.
COMP: Basic arithmetric calculations
(arithmetic operations, trigonometric functions, etc.)
COMPLEX: Complex number calculations
SD: Single-variable statistical calculations
(sample standard deviation, etc.)
LR or REG: Paired-variable statistical calculations
(linear regression statistical calculations, etc.)
BASE or BASE-n: Binary, octal, decimal, hexadecimal number system calculations
MAT: Matrix calculations (determinants, etc.)
VCT: Vector calculations
EQU: nth degree equations, simultaneous equations
2) Display Settings
Use these settings to control how calculation results are displayed.
Note that changing the Fix and Sci settings does not affect internal calculation results.
Norm: Exponential display format and cancels the currently configured Fix and Sci settings.
Fix: Specifies a fixed number of digits to the right of the decimal place.
Sci: Specifies a fixed number of significant digits.
3) Angle Unit Setting
(90°=?/2 radians=100 grads)
Deg: Degrees
Rad: Radians
Gra: Grads
4) Engineering Mode
Use this mode when you want to input and perform calculations using engineering symbols.

Ten zeros when you start

The Fix sign on the top of the screen (smaller size) are indicators that calculator is using the FIXed format: All numbers are displayed with a fixed number of decimal digits (in you case it may have been set to 9 decimal digits). You can change that in the setup.
The Grad symbol means that the angle unit is set to grad. This too can be changed to degrees or radians in the set up.
A sure way to achieve mastery of calculator use is to learn how to configure it to fit the types of calculations to be performed.

Hope it helps.
