There are a couple of things we really need you to stop saying. The first:
“The right answer isn’t important. It’s knowing what you’re doing.”
No matter how you parse this, it’s ridiculous. The right answer is the whole point of doing the problem … has always been, is now, and will always be. The “knowing what you are doing part” leads to the right answer. If it doesn’t, then you don’t know what you are doing.
