It’s sunny today. In general, I’ve put a great effort into math. My dad attaches much importance to mathematical principles, and to English as well. So, he has begun to read me incomprehensible things. For instance, today’s goal was to study estimation by investigating the relative advantages of exact vs. approximate solutions to problems. Also, he explained how to give answers to a specified degree of accuracy. It stumped me for like half an hour just to get a full understanding of the concept. It was way over my head.
