If you plan to learn astronomy, you must learn math well, but fortunately, we have a lot of good math software, such as MATLAB, Maple, Mathematica and so on, which is very helpful for dealing with mathematical calculations. Astronomy departments generally have many directions, such as high energy astrophysics, astrometry, celestial mechanics, cosmology and so on. Especially when it comes to astrophysics, mathematical and physical methods are very important; Astrophysics uses physical methods to study astronomy, so mathematics is very important for the study of physics, such as the content of vector analysis used in mechanics. Generally speaking, it is impossible to meet the needs of modern physics without learning mathematics well. Of course, if you just learn to play, there are physics books abroad that don't use advanced mathematics, and astronomy is the same. Some knowledge of elementary mathematics is enough, but that is a minority after all. If you want to study astronomy in depth, I suggest learning math and physics well. Otherwise, if it is a hobby, it doesn't matter; Hobbies and majors are two different fields. You can do celestial photography or something, and you don't need math. Of course, it depends on what you mean. You can buy some books on astronomy in this respect, which is very different from amateurs.
