Personally, I really enjoyed Mathematics, it was my strongest and favorite subject in school. I love solving riddle and discovering patterns and that is how I see expressions: They are just are fun riddles. Usually I would get an idea about an expression to animate or design something, and I would spend lots of time and effort figuring it out even if I was not going to use for any current projects. Sometimes, I am unable to sleep because i'm thinking of coding ideas. Hence, fun is an element when it comes to learning!
