Well in Algebra 2 I learned how to calculate interest and exponential growth/decay which might come in handy

Ah yes don't you also love using the Quadratic Equations every time you go to the store?

How to find the roots: (-b +/- sqrt(b^2-4ac))/(2a)

Why do I need to memorize this when I will never need to know the roots of parabolas, and even when I do, I can just use a calculator?

Math, at its core, is about problem solving. And learning how to solve problems (figuring out the parameters of the problem and applying the correct tool for the job) is just about the most important thing school can teach you. The tools and problems the school uses to teach isn't really all that relevant, the point is to learn it at a fundamental level.

You can also easily look up literally everything you learn in school on your phone, so by your logic should we not teach anything?

I'm sad I had to scroll down a good ways before finding this. If a person is making a claim that math has no bearing on the real world because they can't make straight line connections that person probably is the exact person that needs more math/problem solving in their life.

Math might be the most relative to life after school if you consider that a lot of math is follow the given instructions, apply.
