Recently, Apple officially issued a recall notice for problematic iPhones. Due to a problem with the built-in calculator function of Apple phones, the calculation function is incorrect. Everyone.

False. Twice of 38.5 is exactly 77, so press 77-38.5 on the calculator on your mobile phone. If you press it again, it is still 38.5. If you press it again, the system will display the result of 77-38.5-38.5, which is 0. If you click again, the result becomes -38.5, and so on. Don’t take this kind of teasing joke seriously
