Starting calculus at a young age, such as 13, is viewed as early but not unreasonable, especially if the student has a solid grasp of basic math. Many participants in the discussion share their experiences of beginning calculus in their early teens, with some expressing that it can be mastered with the right understanding and interest. Concerns arise about the social implications of advanced math study at a young age, with some suggesting that it might hinder social development. However, others argue that it is possible to balance academic pursuits with social activities and that math can be a fun and engaging subject. The importance of a supportive educational environment and good teaching is emphasized, as well as the need for students to pursue their interests without feeling pressured. Ultimately, the consensus is that there is no "right" age to learn calculus, as long as the student is capable and enjoys the subject.
