You HAVE to be loving kidding me, OP.
Algebra. Oh, Algebra. Important stuff. There are so many things you can do with Algebra you can't even comprehend it. Same with Geometry. It isn't all triangles, squares, and stuff, you forgetwit. Simple math, is important as forget. EVERY loving JOB REQUIRES IT. With Algebra and Geometry, EVERY loving JOB THAT GETS YOU MORE THAN MINIMUM WAGE REQUIRES IT. Don't even TRY to argue about "We learned algebra in 4th grade", because you go more indepth. Did you learn about Monomials and Polynomials in Fourth grade? How about Quadratic Equations?
You are stupid.
History. Important stuff. I love history. I love everything about History. If you want to know why History is important, read the book, "The Giver", which is set in the future in a utopian society with no reccolection of their past.
Why don't you look 200 years back, when the average man couldn't get an education, and tell me how it was. forget you.
