Most things in math after you learn the basic functions are things you will forget by 25. You most likely will never use them in your lifetime other than in schoolwork. Language is a great way to try to get students interested in other cultures, but most will never use the language they were taught after graduation. So, after graduation and even between years, school does not make us more intelligent, it tests what we remember even if we will never use it.
Do we really need need to find what x is? What will finding x do in life? Are we accually going to get a question for a job saying 1+ x = 13 Find x
OF COURSE NOT!
So why exactly do we need the course? (Seems useless to me.)
