# How do I do factorials on a TI-84?

$M A T H$ $\rightarrow$ $P R O B$ $\rightarrow$ $4$

#### Explanation:

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

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

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

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