Do Not Remove Bar From Repeating Decimal

The mathematical pun is strong with this one! In the meme, we see "5/6 = 0.83" with a warning sign that reads "DO NOT REMOVE BAR FROM REPEATING DECIMAL." This is a brilliant play on rational numbers - specifically how 5/6 actually equals 0.8333... with the digit 3 repeating infinitely. In mathematical notation, we indicate this with a bar over the repeating digit (0.8̄3). The joke is that if you literally "remove the bar" from the repeating decimal, you'd just get 0.83, which is incorrect! It's the mathematical equivalent of "do not remove tag from mattress" warnings, but with catastrophic numerical consequences. The crack in the wall suggests the fabric of mathematical reality is breaking down due to this egregious error!
