Question about Casio FX-115ES Scientific Calculator

I have a new casio scientific calculator fx83ES and need to do some basic arithmetics (eg. 7/0.8) but i only get to have the answer as a fraction (eg.35/4). How do i get to have the answer in decimals... (eg. 8.75)?

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.

This calculator can do some arithmetic with complex numbers, and it can do some operations with matrices. Unfortunately the two do not intersect. You cannot do complex matrix operations with this calculator.

Sorry if that wasn't the answer you wanted to see. That's just the way the calculator works.

1÷1700 expressed as a decimal is 0.000588235, which is 5.882...×10^-4. [NB not 10^4]

To convert this to a percent, remember that "per cent" means "per 100" which also means "divide by 100". To keep the answer correct, if you are dividing by 100 you must also multiply by 100.

The get the answer in percent, you must therefore multiply the previous answer by 100 to get**0.00588235 percent**. (or 5.882...×10^-2 percent).

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.

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

(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.
