As long as the teaching method suits you, regardless of gender. Generally speaking, it is better to be a man. Because men are thoughtful and rational, they are more talented in mathematics. Moreover, in major universities, it is male teachers who really have certain accomplishments. Female teachers are not bad, but too few good ones. It depends on the individual. Some women are super good at math. But personally, I think it would be better if the math teacher were a man.
