A relevant and insightful slogan for math is, "Math is like life: it is not always about the destination but how you get there." What many math teachers try to teach is not the answer to a math problem but the process by which an answer is produced.
Many students remember getting docked points for providing correct answers to their math homework without being able to show their work in how they arrived at the correct answer. This is because math is really just a process. If a student learns how to use the process, they are able to answer any question thrown at them regardless of its perceived difficulty. This is true in life, as well, where it does not necessarily matter where a person ends up, what is important is the journey they took to get there.
