Editing Equations on a Ti-83+ Calculator

[mark126]

Just a quick question about the Ti-83+ calculator. After you have hit the equals button to provide the solution for an equation, how do you get back into the equation to make any changes? The error key is not what I'm looking for, is it possible to make any changes you want in the equation? I asked my Math teacher and she didn't know, this is for Math 12 in case you were wondering. Thanks!

hit [2nd] [ENTER] and it will give you what your equation was previously, this by the way is second, entry.
