Algebra -sigh

I was enrolled in algebra in high school. Mostly I understood the commutative property and the Pythagorean Theorem as well as others, but it was because I memorized the definitions. In my sophomore year of high school my algebra teacher was woefully under qualified to teach the class. On more than one occasion she would leave the room to go next door to ask another teacher what she missed when teaching the class the lesson. Eventually I dropped this class and took a geometry class instead. As soon as I could drop math classes, I did so and never looked back, until I enrolled in college.
