Everyone always says "Why do I need to learn algebra, I will never use it." That may be true depending on what field you are talking about. To be a real good plumber you need to know a basic level of geometry, algebra, and trigonometry. Same with and electrician or heating and air.

That is not the point. The main purpose is training your brain in problem solving. The more you do it the more you will naturally identify problems and work out solutions in all areas of life. Math is the best tool. Even if you start at arithmetic, it doesn't matter.
