Execute an External Program as a Subroutine on the TI-84 - Depending on what equation you enter, you can name it after the equation, or you can call it whatever you want, but it can only use numbers and symbols and can only be 8 characters long. Calculator programming can even help you learn computer and mobile device programming.

With this tutorial you will be able to program formulas into your calculator ti-83 ease. This is for anyone who wants an easier human-error proof way to derive the answer to several formulas. You can program any formula that uses inputs into your calculator using this process. For demonstration purposes I will be using the coding for the quadratic formula. Remember to include your games by pressing alpha beforehand. This will allow you to set your formula equal to a value such as X. You can store the second value as another variable such as Y as seen below for the easy formula. This is the time to make sure that your calculated value is conclusive with the value that you had previously obtained by other means. If you followed my example of the quadratic equation your ending result should look like what I have on the program above. That will take you back to the main screen where calculations are done.
