    Algebra.

    My mom is a high school maths teacher and she taught me the concept of algebra at a young age. This stuck out to me because I had a teacher in preparatory school who marked me wrong because I didn't use the method he showed us but instead I used algebra. The question was one of those "if Jane gets an amount of pocket money and her Margret sister gets double, and they get a total of R500 combined then how much money does Jane get?" I think we were just supposed to guess or something, I can't remember the method he wanted me to use but algebra was much much simpler. It's the one of the few times I saw my mother get pissed at one of my teacher hahaha
