It’s cloudy today, and it looks like it’s going to rain shortly. There’s been a lot going on recently, and my mind is a bit messy. Among all the things, math is still my biggest issue. Lately, the time I spend on math homework has been increasing significantly. It’s all about the newly learned functions with negative numbers and coefficients. If I had to choose one country I dislike, I’d say it’s Singapore. As far as I know, the hardest math practice problems and materials often come from there, even my test papers.
