Hello,

The **prb** key displays two menus PRB and RAND. The factorial is the third option under the PRB menu.

4 PRB 3 displays 4! which is 24.

Hope it helps.

Here you go, Ray Ray...

In order to calculate the factorial of a number you must do the following:

1. Type your number [8]

2. Hit MATH

3. Scroll to PRB

4. Hit ENTER [The factorial symbol should be either the 1st one on that list or the 4th one]

Longstoryshort, if you want to find the factorial symbol on your TI-83 you must go to MATH. PRB. !. Done

By the way...that factorial is the fastest growing type of function in mathematics, and it is the backbone behind permutation, combinations, and a lot of probability theory.

Have Fun,

8. MATH. PRB. !.

That is how you get the factorial of a number.

The factorial is beneath the PRB list, which is inside the MATH menu.

Adios,

Enter the number whose factorial you want to calculate.

Press the [MATH] key under the [ALPHA]key.

Press the Right arrow 3 times to highlight the [PROB] menu.

Select option [4:!]

Press [ENTER

Note : Due to memory limitation, the argument of the factorial function must at most be equal to 69

Enter the numerator then the division key and the denominator. Before pressing [ENTER], press [MATH][1:=>Frac] [ENTER]. The fraction will be displayed reduced.

27/48 [MATH][1:=>Frac] ENTER] yields 9/16

27/48 [MATH][1:=>Frac] ENTER] yields 9/16

Hello,

There is no key per se but a command accessible as follows

[MATH][1:->Frac] the fractions given are always reduced/

27/48 [MATH][1:->Frac][ENTER] gives 9/16

0.25 [MATH][1:->Frac] [ENTER] gives 1/4

Hope it helps
