How do I do factorials on a TI-84?

1 Answer

Oct 29, 2015

$M A T H$ $MATH$ $\to$ $rarr$ $P R O B$ $PROB$ $\to$ $rarr$ $4$ $4$

Explanation:

First, hit the $M A T H$ $MATH$ button on the calculator. It is located under the $A L P H A$ $ALPHA$ button.

Next, use your right arrow key to scroll to the $P R O B$ $PROB$ tab. This stands for probability.

Then, you can access the $!$ $!$ symbol by either hitting the number $4$ $4$ or using your down arrow key until you get to the symbol.

The $!$ $!$ can also be found in the $C A T A L O G$ $CATALOG$ , which has a different path to get to.
