Useless to you. I extremely need to know the Pythagorean Theorem for my work. Actually, absolutely everything I have ever been taught in math class ever, literally all of it and so much more, I have used. But I’m starting a PhD in electrical engineering in the fall, so I’m a bit biased 😆.
For me personally, dissecting frogs (well actually I dissected a clam) was probably a waste of time, but for at least some of my classmates it was probably helpful. Long division is important because it stimulates algorithmic thinking, which is important for living in a computerized world. Area of a trapezoid is important because… sometimes trapezoids show up, or you can approximate a more complicated shape with a trapezoid whose properties are well understood.
Agreed. My point was more that I didn’t really learn much from actually dissecting a real animal. Like I probably would have learned more from reading a book or watching someone else do the dissection.
