There's a cube root function in the MATH menu. As an example, to calculate the cube root of 125, press MATH 4 1 2 5 ENTER .

Somehow you're calculating 12!/(5!/7!).

Press 1 2 MATH left-arrow 4 / 5 MATH left-arrow 4 / 7 MATH left-arrow 4 ENTER to calculate the desired value. Alternatively, you can press 1 2 MATH left-arrow 3 5 ENTER or 1 2 MATH left-arrow 3 7 ENTER to calculate the same thing.

For negative numbers (not just exponents), make sure you use the (-) key just to the right of the decimal point key, not the - key for subtraction.

For what follows I'm going to assume you have at least version 2.53 of the operating system for the 84Plus. If you have an older version, I STRONGLY recommend you update it:

http://education.ti.com/educationportal/sites/US/productDetail/us_os_84plus.html

You can use the "n/d" command in the MATH/NUM menu to enter the division bar. For example, to enter 1/2, press 1 MATH right-arrow ALPHA [D] 2 ENTER. If you just want the number, you can also enter it as 1 / 2.

You can convert a decimal number to a fraction using the >Frac command in the MATH menu. For example, to convert 0.2 to a fraction, press . 2 MATH 1 ENTER.

For cube roots, use the cube-root function in the MATH menu. For example, to calculate the cube root of 8, press MATH 4 8 =

For other roots (including cube root), use the xth-root function in the MATH menu. For example, to calculate the fifth root of 32, press 5 MATH 4 3 2 =

There isn't one. You can convert some values to fractional form by using the >Frac command on the Math menu available by pressing the MATH key. You can enter a fraction as a quotient, but the calculator deals with the number internally by converting it to decimal form.

For example, to see one-half plus one-third, press

( 1 / 2 ) + ( 1 / 3 ) MATH 1 ENTER

For example, to see one-half plus one-third, press

( 1 / 2 ) + ( 1 / 3 ) MATH 1 ENTER

Hi,

You can write a fraction by dividing an integer number by another but it will not be displayed as you enter it. It becomes a decimal number.

However, if you want to keep it in fraction form (but reduced to its simplest form) you use the command [|=>Frac] . The arrow is a short, fat one.

To access the command

Press [MATH][1:ToFrac] [ENTER]

Ex: you enter 27/48 [MATH][1:ToFrac][ENTER]

Calculator displays 9/16

So you can keep numbers (in reduced form) by inserting [MATH][1:ToFRac] before pressing the [ENTER] key.

Hope it helps.

Thank you for rating the solution.

Hello,

You get access the command by pressing [MATH][1: |->Frac].

If you want enter a fraction and keep it as a fraction (albeit a reduced one)

key in the number then the sequence [MATH][1: |->Frac]., then [ENTER].

Practice : 27/48 [MATH][1: |->Frac] [=] gives the reduced form 9/16.

While this fraction is still in [ANS] memory, you can press [MATH][2: |->Dec] [=] to get the decimal value 0.5625

Hope it helps.

Hello,

There is no fraction button. Any division of two integers you do is represented as a decimal number. If you want your fraction to remain a fraction you enter it as follows

**7[ / ] 19 [ MATH][1:ToFrac] [=] displays 7/19**

If you want to convert a decimal number into a proper fraction press**[MATH][1:ToFrac] .**

Exemple 7/19 [ENTER] gives .36842105. If without doing anything else, you press [MATH][1:ToFrac] you recover 7/19.

There are limitations related to the number of decimal digits in the floating point number.

.3684 [MATH][1:ToFrac][=] gives 921/2500 but

.36842 [MATH][1:ToFrac][=] gives .36842 : it is not converted to fraction.

Hope it helps

Functions on the calculator are **bold**. Numbers you choose are in *italics*.

For random positive integers between 0 and*n* use the following:

**int** (**rand** * *n*) + 1

**int** is on [Math] [Num] F4

and**rand** is on [Math] [Prob] F4

**rand** returns a random number *x* between 0 and 1 such that 0 < *x* < 1.

**int** returns the integer portion of a number such that **int** 123.456 returns 123 and **int** -123.456 returns -124.

For random positive integers between 0 and
