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

When you perform an arithmetic operation such as addition, subtraction, multiplication, or division the result has a specific name. The result of addition is called the** sum;** the result of a subtraction is called the **difference**; the result of multiplication is the **PRODUCT**. Finally the result of a division is the **quotient**.

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.

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).**

Actually, the answer is 79.

The fx-115ES does not have a key for the modulus operation. Nor does it have an integer-part or fractional-part operation. However, it is possible to calculate the remainder using integer arithmetic.

Press MODE 4 to shift into integer mode. Then type in 3 5 2 - 9 1 * ( 3 5 2 / 9 1 ) = and see the answer 79. It's a pain as both numbers have to be entered twice, but it does get the job done.

To get back to working with real numbers again, press MODE 1 ( or MODE 2 for complex).

Press MODE then 4 to select BASE-N mode. Press SHIFT log to select binary mode. Use the digits 0 and 1 to enter numbers.

You can do basic arithmetic as normal. You can access additional functions by pressing SHIFT 3 to select the BASE menu.

The calculator has two Input/Output modes: the default MthIO (new) and the old LineIO.

If you use the default MthIO you can let your calculator perform the operations in exact arithmetic. When you obtain the end result, you can easily convert a fraction/radical result into a decimal one by pressing the [S<=>D] key, or press [SHIFT][=] instead of [=].

However if you do not care about the MthIO and its nifty functionalities, you can configure your calculator to use LineIO.

To set LineIO press [SHIFT][MODE][2:LineIO]

- In MthIO you enter fractions and radicals as you see them in textbook (multiple levels). Calculations are exact and results are generally a mixture of fractions and radicals.
- In LineIO, numbers are entered the old way and all numbers, operations are written on a single line. All fractions and radicals are converted into decimals numbers.

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

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

There is a button there that says "S<=>D". Compute it first and when the result is in fraction, press this and it will be in decimals. This button is just above the DEL button.
