Meme Me Up, Scotty!

Every now and then on Twitter or Facebook there’s a math problem posted which challenges users to get the right answer. They’re almost always based on order of operations and the reason most people get them wrong is because they don’t remember that elementary rule. It’s hard to blame most people since a lot of math that’s used day to day doesn’t require order of operations.
