Our Math G1 class this semester was harder to understand than our English class. These are the words I noted during the "Sketching Graphs" lesson in math. For me, it was very hard to understand the problems without knowing these words. (Believe me, the same thing happened during the thermodynamics and statics (physics) classes in the first 1-3 weeks of the semester 😅)

supremum
refinement
subinterval
