Unlike the elegant divisibility rules for 2, 3, or 5, checking for divisibility by 7 feels like filing your taxes with a broken calculator. That convoluted "take the last digit, double it, subtract from the rest" trick is mathematical torture that even calculators were invented to avoid. And just like Bernie's persistent campaign messages, this rule keeps showing up in math classes despite everyone silently agreeing we'd rather just do the long division. Pro tip: if you've spent more than 10 seconds applying the rule, you could have just divided the damn number already.
