Question about Casio FX-250HC Calculator

Ad

Hi,

You must change the number display to FIX. Press [MODE][7:] followed by a number betwee 0 and 7. This will set the number of decimal digits. Be warned that the Indicator FIX will be displayed on the screen.

This information is for the FX250D, but I trust it is also valid for the FX-250HC. If it is not, just look in your manual. If you cannot find yours, do not blame me, I cannot get hold of a manual for this calculator.

You can always take the time to play with the [MODE] key followed by [.] or a number. When you press the mode + number, look on the screen to see what indicator appears (deg, Fix, Rad) The one that makes FIX appaear is the one that gets you out of the exponential scientific mode.

Good luck

Press 1 E 4

The E means "times 10 to the" so 1E4 is 1*10 to the 4th 10 to the 4th.

You cannot use a letter as an exponent, unless you stored a numerical value in memory B (EX: 3 [STO>] [ALPHA] B stores value 3 in B)

For any numerical value of exponent ( positive, negative, integer, fraction, what have you) you use the general power key, marked with a caret [^] under the [CLEAR] key.

Example: To enter 15 to power 5

Type in 15

Press [^] key

Type in the value of the exponent (5) and press [ENTER]

You get 759375 as result.

To enter powers of 10 you use the [EE] key.

EX: 1.07 x10^(38) type in 1.07[EE]38 [=]

Press [2nd][,] to activate (EE) which appears on screen as a lower case E, enter the change sign (-) right of the [dot] on the bottom row of keys, enter the value of the exponent.

Ex: Enter Avogadro's number of Generalk Chemistry fame

6.02[SHIFT][,] (EE) (-)23

Here is screen capture of what it will look like.

To extract the roots of orders higher than 2, you can use the universal power key labeled as [Y to x]. if the exponent is an integer 3, 4, 5, 6 etc.

it gives the cube the 4th power, 5th, 6th, etc.

If the exponent is 1/3, 1/4, 1/5, 1/6 you calculate the cubic root, the 4th root and so on.

When you use it to calculate the roots, the radicand (the number the root of which you are calculating) must be positive, otherwise you may get the result as a complex number.

The syntax of the command is value [Y to x] (1/ order of root)

Ex: cube root of 27 is entered as 27 [Y to x] (1/3)

it gives the cube the 4th power, 5th, 6th, etc.

Hi,

You have a key labeled [Y to the x], use it for all the powers or roots that do not have a dedicated key or key sequence. Let the key be [^]

Ex: 13.675 to the power 1.33 is entered as 13.675 [^] (1.33) [=].

The result is 32.41778634

Ex: (-64)[^](2/3) [=] gives 16 as result. The (-) is the change sign key

Ex: (2.87655)^(-6.778) is entered as 2.87655 [^] ( (-) 6.778 ) [=] 0.0007758

The (-) is the change sign (or the negative of), not the regular minus. When you have a negative exponent or a complicated exponent, it is safer to enclose the whole exponent inside parentheses.

Hope it helps.

Thank you for using FixYa

To enter a number in scientific notation use the [EE] key. Press the change sign key [(-)] before entering a negative exponent.

Ex: Enter the .lectron charge 1.6 *10-19

1.6 [EE] [(-)] 19 [ENTER=]

Ex: Enter the .lectron charge 1.6 *10-19

1.6 [EE] [(-)] 19 [ENTER=]

that must be because you calculator is in scientific/eng mode. press [MODE], then select normal.

You can download the guidebook for this calculator from TI here.

From page 16:

To enter a number in scientific notation:

1) Enter up to 10 digits for the base (mantissa). If negative, press the +/- key. (The key has two curvy arrows between the + and - but I can't do that on my keyboard.)

2) Press the EE key.

3) Enter a 1 or 2-digit exponent. If negative, press +/- either before or after entering exponent.

They give the example 1.2345 +/- EE +/- 65 which would display -1.2345 -65.

there is a ^ aboe the divided sign. you can use that

ex x^4-x^3+x^2

ex x^4-x^3+x^2
