I saw a basic Algebra problem once that gave the illusion that 2=1, after doing normal inverse operations and properties of equality steps. I know it camoaflagued zero as a variable somehow then divided by that variable, but it isn't obvious to the beginner that said variable is actually zero. DOES ANYONE KNOW THIS PROBLEM WENT? I can't seem to remember anymore than I have shared. (All the steps need to be understandable to Algebra I students).
