Clever Math Factorial Pun Meme

This is a screenshot of a social media post featuring a two-layer math joke. The post first asks viewers to solve the calculation 230 - 220 x 0.5, then claims the answer is 5. Most viewers initially misinterpret the exclamation mark as regular emphasis, thinking the poster incorrectly states the result is 5, but the exclamation mark is actually mathematical factorial notation. The correct result of the calculation is 120: following order of operations (PEMDAS/BODMAS), 220 multiplied by 0.5 equals 110, and 230 minus 110 equals 120, which is exactly the value of 5 factorial (5! = 5 * 4 * 3 * 2 * 1 = 120). The joke relies on viewers forgetting or missing the factorial notation.
