What grinds me the most is we're sending kids out into the world who don't know how to balance a checkbook, don't know how to apply for a loan, don't even know how to properly fill out a job application, but because they know the quadratic formula we consider them prepared for the world` With that said, I'll admit even I can see how looking at the equation x -3 = 19 and knowing x =22 can be useful. I'll even say knowing x =7 and y= 8 in a problem like 9x - 6y= 15 can be helpful. But seriously, do we all need to know how to simplify (x-3)(x-3i)?? And the joke is, no one can continue their education unless they do. A student living in California cannot get into a four-year college unless they pass Algebra 2 in high school. A future psychologist can't become a psychologist, a future lawyer can't become a lawyer, and I can't become a journalist unless each of us has a basic understanding of engineering. Of course, engineers and scientists use this shit all the time, and I applaud them! But they don't take years of theater arts appreciation courses, because a scientist or an engineer doesn't need to know that 'The Phantom of the Opoera' was the longest-running Broadway musical of all time. Get my point?
