Question about Casio fx-300ES Calculator

Ad

On old calculators fraction elements are separated by what you call a "backward L". If there is only one "backward L", the number to its left is the numerator, and the one on its right is the denominator.

If you have two "backward L", you are dealing with mixed numbers: The first number (to the left) is the integer portion. The number in the middle is the numerator of the fraction part, and the last number is the denominator of the fraction part.

Ex: 3 1/2 appears as 3 u 1 u 2. Here u stands for your "backward L".

As to your "various other problems with other keys" I am sorry I cannot imagine what you mean you will have to say more.

If you wan to see stacked fractions (multi-level ones) as you enter them, set Input/Output mode to MathIO. To do so, press [SHIFT][MODE] and select [1:MathIO].

If you do not want stacked fractions, press [SHIFT][MODE][2:LineIO].

Your problem is not with the scientific display, rather it is with decimal representation (approximate) or fraction/radical (exact). representation.

If your results are in fraction/radical form press the [S<>D] key to switch from one to the other.

The calculator is by default in the MATHIO t output mode: results are in fraction/radical form.

If you don't like to work with this mode just change the IO mode to LineIO. To do so, press [SHIFT][Mode](Setup) and selct** 2:LineIO**

Make sure you use the (-) key in the left column above the RCL key to enter negative exponents, not the - key which subtracts.

Do get all results in decimal instead of fraction notation, press SHIFT [SETUP] 2 to select LineIO mode.

If the result is already calculated and displayed, press the
[S<=>D] key It will convert a fraction or radical to decimal. This
is always possible. If the result is decimal it may be converted to a
fraction or a radical (Not always possible).

If the expression to be evaluated is still in the command line and you have not pressed the [=] key, you can force the result to be displayed in decimal format by pressing [SHIFT][=] instead of just [=].

More permanently. If you do n o care for fractions and radicals, set the Input/Output mode to LineIO. To do do press [SHIFT][MODE] to access the (SETUP) screen and select [2:LineIO]

Once a result is displayed you can convert it from fraction to decimal by pressing the [S<=>D] key.

Alternatively, press the keys [SHIFT][=] to get a result instead of just [=].

You can also configure Input output mode of calculator to LineIO and you will not get fractions nor radicals, just decimals.

To set LineIO as the default IO mode press [SHIFT][MODE][2:LineIO].

Hello,

If you call a simple addition a problem it is no wonder that everything seems so difficult.

When you calculate the** sum **6.11 +6.11 , the calculator gives you a fraction reduced to it simplest terms, **611/50**. The result is correct, but it happens that you want it
expressed as a decimal rather than a fraction. To fix that all you have
to do is to press the button **[S<->D] ** above the red [DEL] key. It allows you to toggle the display format between fraction and decimal.

611/50 [S<->D] changes display to 12.22 and if you press the key again you go back to fraction

12.22 [S<->D] 611/50

Similarly, if you enter square root of 2 and it displays as a radical, you convert it to a decimal by pressing the key [S<->D].

The fraction and radical formats allow you to do exact claculations. But if you do not want to hear about that you can just press [SHIFT][MODE][2:LineIO] : Your calculator will do things the old way, but you will lose some important functionalities.

My suggestion is to set the default mode [MathIO] by pressing [SHIFT][MODE][MathIO] and to press the [S<->D] key to convert to decimal.

Hope it helps.

To change from Fraction display to Decimal display on the Casio fx-300ES (and probably other calculators)

1) Press the "SHIFT" button

2) Press the "MODE/SETUP" button

3) Press the "2" button

This Changes it to LINEIO (Decimal)

Doing all of the above but pressing the "1" button instead of the "2" puts it back into MATHIO mode (Fraction)

Hope this Helps

(SHIFT)(MODE/SETUP)(2) to change to decimal
