My students have no trouble remembering PEMDAS, and they have no trouble remembering " Please Excuse My Dear Aunt Sally." But some of them have a TERRIBLE time remembering what those letters stand for. So I made these signs which incorporate the operator into the visual, to help them connect PEMDAS to its actual purpose. You could easily make this yourself, but why bother when I've already done it? It's helped me, and I hope it helps you too! This is just a small thing, and so it's free.
