That's The Mistake I Made When I First Saw A Double Factorial

The mathematical carnage behind this meme is both hilarious and terrifying! In math notation, 10!! (double factorial) means multiplying only even or only odd numbers up to 10, so 10!! = 10 × 8 × 6 × 4 × 2 = 3,840. But if you mistakenly calculate (10!)! (factorial of factorial), you're computing the factorial of 3,628,800... which is a number so astronomically large it would require scientific notation with over 40 million digits. No wonder we'd have flying cars and utopian cities—we'd have unlocked computational power beyond imagination! The difference between these two operations is literally civilization-altering.
