Numbers
Astrophysicists apply their knowledge of maths to solve problems about the Universe. They collect information using telescopes, and use maths and statistics to interpret the information. Astrophysicists also use mathematical models and formulas to understand the physics of the Universe. We would not have been able to discover black holes or know that the Universe is expanding without maths.
Astronomers use numbers all the time (especially really big ones!). Astronomy grew out of solving problems about time and distance.
History
Perhaps you are more interested in history but like astronomy as a hobby? Well, there are careers looking at the history of astronomy, both ancient and modern.
If you love history and astronomy, then these jobs might interest you: Historian (Astronomy, Science or Cultural), Author, Museum Curator, Librarian, Archaeoastronomer, Conservationist, Anthropologist. Many people working in this field, work in both a physics and an arts department.
You may think that astronomy, a science, and history are poles apart. In fact, many astronomers love history, and many historians are interested in space.
