While having a degree or relevant qualifications can be beneficial, there are websites and platforms where you can participate in solving math problems or tutoring without formal credentials. Some websites, like freelancing platforms or online tutoring websites, may allow you to showcase your skills and build a reputation based on your performance. However, it's important to demonstrate your proficiency and reliability to potential clients or employers. You can create a strong profile, provide evidence of your math skills, and gain experience through smaller tasks or projects. Building a portfolio and seeking out opportunities that align with your expertise can help you make a decent income even without formal qualifications.
