How do I get my answer to stay displayed as I type the next input?


You can use the replay button to display the last command entered, then move cursor to the end of the command line and append the part you want to add. But it must be a part of the same command line, with correct syntax.
As to the last result calculated, it is stored in ANS memory. It will be overwritten by the new calculated value.

My caluculater is not onning?


Is it possible you might have reduced the contrast too much that the display ceased to be visible? or you are using it in dark place where there is not enough light to power it up?

Push the ON key.
Press SHIFT MODE to enter SETUP.
Push the Down Arrow of the Replay button.
Press the 6 key
Press the Right Arrow to increase the contrast.

It is possible that this does not solve your problem, because I just reduced the contrast of my calculator and I can still see the display. contrast.

You can also try to Reset the Calculator.
Press the ON key.
Press SHIFT 9
Press 3: to reset ALL
Press = to validate.
The screen should darken.
Press AC key to clear display.

Use the Replay buttons. If necessary, use UpArrow to bring the cursor on the command line, then use the left arrow to backspace. Press DEL button to delete the character following the cursor.

Is there a constant function in casio fx83es


I do not think that this function is implemented on this calculator. But that should not be a problem. You can use the replay function to display the command line for editing. When the previous command line is displayed use the cursor key to change the second multiplicand (for multiplication).
That may not what you want, but I was just trying to show you a workaround. Feel free to use it.

Hi a ritha,
If you are talking about the FX-300MS calculator, the ^ button should be there just below the large "Replay" button, on the immediate next row, slightly to the right. After pressing that, write "-2" withing brackets, like this (-2). The * function is in the number pad below, as you know. If your calculator really doesn't have the ^ button below the Replay button, it is probably faulty. Go exchange it for a new one.

How to convert log


Hello, The first remark is this. The ratio log(0.8)/log(2) is by definition binary log of 0.8 ( meanibg log in base 2 of 0.8) The second remark is good news for you.: When in MathIO, [SHIFT][MODE][1:MathI0], your calculator can compute directly the log in any base of any number. To use the functionality, you press the key below [ON]. It is a log symbols with a small solid square, and and erect empty rectangle.
When you press the key the screen shos a template. In the smaller and lowered square goes the base (here 2). When you enter the base, press the right arrow to move cursor to the rectangle inside the parentheses and type in 0.8. Use the right arrow to move the cursor out of the parentheses.
Practice: try that. the result should be -0.321928095. Good. Now use the replay button to move cursor to the command line outside the right parenthesis. I am going to give you the other key stokes. Let log(2,0.8) be my representation for log in base2 of 0.8. Then you enter the rest of the calculation as
log(2, 0.8) [*] [ ( ] [(-)] 0.321 [ ) ] [*] 2500 [=]
Here [*] is the multiplication sign [(-)] is the negation (change sign), just above the [RCL] key.
[ ( ] is the left parenthesis and [ ) ] its matching right parenthesis. Both of them enclose the number -0.321. It underlined them for clarity.
The result should be 259.0716344
If you do not like what I did above, you can always do things the old way. You use the log key just above the [COS] key. In that case -0.3219*[LOG] (0.80)/[LOG] 2 * 2500. Do not to supply the ) for both log. The calculator inserts the left ones by default.
Hope it helps.

Log I do not know how to...


I have finally worked out how to do log to the base 2 on my FX-83ES after nearly 2 years.
I hope yours is a similar problem.

The calculator must be in MATH mode or it will not work.
press the log button as the useless manual says then 2 then the right arrow on the replay button and then the number you want the log2 off..
Hey presto a correct answer
