(4*6)+2 = 26

(6/2)^(6/2) = 27

6*6/2 = 18

When I type 12!/5!7! I'm getting 2.01180672e10. My answer is suppose to be 792. Please help.

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.

I need help...i dont know how to put in exponents, negative exponents and i dont know how to put in fractions

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:

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.

How do you calculate the cubed root of a number or 5th root of a number?

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 =

Where is the fraction key on this calculator?

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

How do u write a fraction on here

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.

Fractions on my texas tI-83

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.

Where is the fraction button on the ti 83 plus cac. look like

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

How do I get the Ti 85 to do random integers?

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.
