Americans are retarded. Common core education is a failure, especially in maths and history. "Tricks" and "small tips" like these in math show the absolute state of public education. "Tricks" of memorizing the fucking the entire unit circle instead of just the 30-60-90 triangle or memorizing physics equations and just putting the values in exams. At this rate jews will have fully niggerized the brain of americans thanks to chink phone apps and WEF politicians in 10 years
