What humans learn at an earlier stage of learning or education is likely to be erroneous. As knowledge, education and learning grow errors diminishes with unlearning. Learning at a later stage is obviously better than that at an earlier stage.
Having different interests people take interest in different things. It happens in learning and education too. But some skills are so useful that everyone needs a minimum learning in it. Mathematical skills are such skills.
Teaching and learning mathematics are important parts of education. It is comprehensible that everyone cannot take a lot of interest in mathematics, not because mathematics is more difficult than the other subjects, but because people have different interests.
