Automated grading Memes

Welcome to the twilight zone of mathematics education, where the correct answer is wrong and the wrong answer is correct! In the top image, the student writes "7" but the system demands "√7" (which is completely different). In the bottom image, the poor kid writes "√20" and gets marked wrong... with the correct answer being... wait for it... "√20"! This is the digital equivalent of your professor saying "I want your exact thoughts on this topic" and then failing you for not reading their mind. These automated math systems are clearly programmed by people who failed the Turing test. Next they'll be asking for the value of π and rejecting "3.14159" because they wanted "approximately 3.14".
