I need a list to reference when solving for a variable in any algebraic problem. For example, solve for y: 1=e2y. You'd go down the list looking for the function enm and right next to that, you'd see the function needed to undo that function at least partially. Then, with whatever you're left with after applying that, you'd go down the list again repeating the same steps until Y is alone. I can't possibly be the first person to think of using such a list. Therefore, it must already exist somewhere. I can't find it on google though.
