The calculator will turn on and off and will perform all the basic arithmetic functions (+,-,x,/) but only with 1 and 0 with the resulting answers in binary format. Nothing works to get the calculator out of binary mode. The mode switch does nothing. I only have on off, 1,0, and the arithemtic function keys that work. How do I rstore the normal function of the calculator?

I had the same problem myself and tried to follow the instruction posted by -ky- but did't work many times. The reason is the instruction is missing one more step after pressing mode and 1. Finally, after trying so many times (I know back in my mind that, somehow -ky- is on the right track), the complete solution is: press MODE (hold) and then 1, then let go both and then, press 1 again, right after you let go MODE and 1. I can guarantee that this will work because it worked for me. Now I can keep on changing mode from binary to decimal and vice versa, by following the instruction above. Example, if I am now in decimal (RAD or GRAD or DEG), to change to binary, I simply press MODE (hold) 2 (let go) 2. To change back to decimal, press MODE (hold) 1 (let go) 1. Viola, you are back in decimal. Good luck.

This always gets me on the 20S, because you would think using the "SCI" or "ENG" buttons would work. You first have to set it to "DEC" if you're stuck in HEX. On my calculator it's the blue mode shift key (blue left pointing arrow) then 5 (DEC). From there you can change to scientific notation, or whatever.

To convert the calculator from "dec" mode to " Bin","oct","hex" or the ob set

by press "DRG" then number "2" or "3"or "4"

This worked for me, even on the f602

Dont know what you are saying.

Basically turn it off and on if your stuck.

You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

If this doesn't do it, please reply to this post and give an example of something you're trying to graph.

You're in the BASE-N mode, which allows you to do integer arithmetic and logic in a variety of bases. To get out, press MODE and then select the desired mode. 1 is for "normal" computations, 2 is for complex arithmetic, 3 is for statistics, 4 is the BASE-N mode, 5 is for equations, 6 is for matrices, 7 is for tables, and 8 is for vectors.

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).**

The fx-115ES does not have a modulo operator. However, it is possible to compute the remainder using integer arithmetic. Press MODE 4 to shift into integer mode. Then calculate A modulo B as

A - B * (A / B). For example, to calculate 41 modulo 6, press

4 1 - 6 * ( 4 1 / 6 ) =

and get 5.

Press MODE 1 to return to real arithmetic.

A - B * (A / B). For example, to calculate 41 modulo 6, press

4 1 - 6 * ( 4 1 / 6 ) =

and get 5.

Press MODE 1 to return to real arithmetic.
