Question

How do I do factorials on a TI-84?

Answer 1

`MATH` `rarr` `PROB` `rarr` `4`

Explanation:

First, hit the `MATH` button on the calculator. It is located under the `ALPHA` button.

Next, use your right arrow key to scroll to the `PROB` 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 `CATALOG`, which has a different path to get to.
