In this instructable, I will show you how to write a program on your calculator that will do Heron's formula for you.

This is a link to my Quadratic formula program instructable.  You will probably find this instructable helpful too.

Step 1 Getting Started

First, you push the program button.  Then push the right arrow twice and hit enter.  Now enter a name using the alpha key (the green one).  When you finish entering a name, hit enter.
