I firmly believe that one of the failings of the way we teach most subjects is that there is a very low amount of application. Grinding away and learning the theory is almost useless; for most people as soon as they move on it's out of their head and gone forever, with maybe a ghost of a memory that the topic exists. It's a shame, because some of these things are valuable to know. If you're felling a tree, trigonometry is pretty useful for trying to figure out whether you've got room to drop it without hitting your house. Also, when you're building that house, for how long you need to cut your rafters to get the right pitch on your roof. You don't necessarily need to know chemistry to cook, but it doesn't hurt, and you'll understand why you need to use baking powder instead of baking edit: soda when you bake your biscuits. There's a lot of basic physics and mechanics that can be incredibly useful if you're trying to lift heavy objects with less than adequate equipment.
