Prefixes such as milli already reflect the corresponding multiplier or divisor. One milliamp is 1/1000th of an Amp, so 37 milliamps = 0.037 of an Amp.To keep two sides of an equation the same, you need to perform the same operation on each side. In this case, the equation is 37/1000 = 0.037. The "divide by 1000" part of this equation is included in the word "milliamp", hence 37 milliamps = 0.037 Amps.Another way of looking at it is that a number remains unchanged if you both divide and multiply it by the same number. In this case, changing to milliamps is dividing by 1000, so you need to multiply by 1000 to keep the result unchanged.You have actually divided by 1000 twice as a result of using x10^-3 as a multiplier when you should have used x10^3

for 1-Var statistics Press [MODE][3:STAT] [1:1-VAR]. You are ready to enter values in the X column. Enter a number and press [=]. Cursor jumps to second number to enter.Keep entering numbers and pressing [=] till all numbers are in. Press the [=] key after the last one.Press [AC] key to clear the screen.Press [SHIFT] [STAT] (above digit 1.) then [5:Var]. Screen displays the statistical variables 1:n ;2: x bar; 3: x sigma n; 4:x sigma n-1.Press the number corresponding to Referable you want, ex 1:n . The variable appears on screen. Press [=] and it will be displayed.To display another variable press [SHIFT][STAT][5:Var][ 1,2, 3, or 4] .To access the sum of squares sigma x^2 and the sum of data sigma x press[SHIFT][STAT][4:SUM] then [1: for sigma x^2] or [2: for sigma x]. Press [SHIFT][STAT][6:MinMax] to access minX and maxX.For 2-var statisticsTo perform 2 variable statistics you press [MODE][3:STAT] and any of the other regression options (except 1:1-Var). A two column template opens where you enter the X and Y values. When finished entering data, press [SHIFT][STAT][5:Var]. to access the different statistics. you should be able to recognize what each variable means.

Set the default IO mode to MathIO.Press [SHIFT][MODE] to enter (SetUp). Select [1:MathIO]

To convert a single value from symbolic to decimal, press the S-D key (just above the DEL key). To have all results come out in decimal, press SHIFT MODE 2 to switch to the LineIO mode.You can download the manual and the appendix here.

You cannot remove it. You can only deactivate it. Press [SHIFT][MODE] to enter (SetUp). Select [1~LineIO]

variance is 11.38

Change the Input/Output Mode to LineIO. Press [SHIFT][MODE] and select [2:LineIO].

Set the Input/Output mode to LineIO. To do so, Press SHIFT MODE, then select 2:LineIO.

Sorry! not enough memory on the calculator to store games. Also no port to transfer them. Get a PSP, iPad, etc.

The calculator has two Input/Output Modes: The MathIO and LineIO modes. Line IO is the old input mode where all symbols are written on a single line. MathIO permits fractions to show as they would in a textbook (a horizontal fraction bar and two squares, one on top and the other at the bottom. Pi can be used as Pi and irrational square roots are displayed with the root symbol. etc,,
If you are in MarhIO and you get a result with fractions, radicals, or pi. you can readily convert it to its decimal approximation by pressim the SD key. If you enter some expression with fractions and radicals and you do not want the result displayed with fractions or radicals you press SHIFT = instead of =,
Now if you do not care to have ANYTHING displayed as a fraction, radical or with PI, just set the IO mode to the old LineIO.
To effect that, press SHIFT MODE to enter the SETUP. Select 2:LineIO. From that moment on you will no longer see a fraction, nor a radical nor PI, e,

If you ever reset the calculator, the MathIO mode will be restored as default IO mode.

There are three ways to enforce the changes, and it is quite impressive for this calculator. Yet for you it is not enough. I am sorry but I am not aware of another way.

Maybe, just maybe, if you fixed the number of decimal digits to 0, all your results will be integers, and there won't be any reason to convert any result to a decimal and the problem will be solved.

Do you really need a calculator to solve a linear equation? Let us see how to solve it without a calculator.Remove the parentheses fronm the second term on the left : y-3Use the distributive property on the last term on the right side -2y-6Take the term -3 to the right side, changing its sign in the process (becomes +3)Take the -2y term to the left making it +2y.3y +2y=18+3-6 or 5y=15 and the answer is straightforward .As to your Casio FX300ES, it cannot solve equations because it does not have an EQUATION calculation mode. The Casios FX-115ES and FX-991ES have an Equation Mode. If you use any of the two to solve an equation in one variable (linear, quadratic or other) the unknown is taken to be x by default. You would have to change the name of the variable from y to x.

For the basic functions it is exactly like any calculator. Press keys to enter a number, press an operation symbol (+, -, x , /) then the equal sign.
For the more advanced functions and functionalities I am afraid you will have to consult the manual. The appendix has examples for each type of advanced calculations.

Press SHIFT MODE to enter SetUp and select another display option: Normal or Fix.

Press 8 [*10^x] 6 / 4 [*10^x] 3 =

[*10^x] is the key just below the 3 key.

x is the height of tree, y and z are as denoted in picture:

1. cos(22°)=y/215==>y=cos(22°)*215=199.3 ft
   
2. sin(22°)=z/215==>z=sin(22°)*215=80.5 ft
   
3. tan(52°)=(x+z)/y==>x+z=y*tan(52°)=255.1 ft
   
4. x=255.1-z=255.1-80.5=174.6 ft

Please rate my answer if it was helpful :)

It's 3/31=0.09677419355

It's 26/48*100=54.16667%
