I had an equation that made perfect mathematical sense, but my dog ripped it to shreds. Fortunately, I've managed to recover all of the pieces to the equation, but I can't seem to remember how they were arranged.
Everything in the braces below must be used in reconstructing the formula (other than the braces themselves). You can arrange them in any way you want, provided that you don't change their actual shape or orientation (for instance, a + is not the same as a x). What was the original equation?
