title: TI-Basic: How do you get an equation as an input?
body: <p>I was playing around with programming on my TI-84 in math class today and I decide to try to write a program that reads an equation and than does a few things with it. But I'm having trouble reading an equation. I tried <code>:Prompt Y1</code> but I kept getting a data type error when I try to use the program. Does anyone have any ideas on how to accomplish this? Thanks in advance.</p>
