Now the genetics and nutrition of the brain are almost the same. There is no such thing as being stupid. I can only say the development potential of IQ and EQ in your mind when you were a child.

Mathematics is logical thinking and digital creative thinking. We can find the target in different ways. But in fact, mathematics in exam-oriented education is just the way the teacher teaches you. The more ways you solve problems, the more likely you are to solve them. Real mathematics is actually far more than what you learn from books. Mathematics includes not only numbers and letters, but also figures, shapes and spaces. Those are more interesting math. In fact, mathematicians, like artists, are all creative thinking.

Don't think that you are stupid if you don't learn math well. Many times, your ability may be in other aspects, such as language, such as communication, such as writing, such as hands-on ability and so on.
