But at higher you also learn how to solve problems. Suppose you see a problem which is quite unfamiliar, you have tools and you know how to use tools- combine tools, separate those and use for separate parts, invent tools, etc.
This is a good argument for, "why do I need to learn math/science? I'll never use it."
Maybe you won't need to factor polynomials daily, but knowing how to solve that kind of problem can be applied to other scenarios outside of Algebra II.
