No, advanced mathematics is not a prerequisite for learning how to code or building a platform like the one you described. While some programming concepts may involve mathematical concepts, you can still learn to code and build a platform without having a deep understanding of advanced mathematics. However, having a basic understanding of algebra and logic can be helpful when learning to code.
If you're starting from scratch, there are many resources available online to help you get started. Some popular websites for learning to code include Codecademy, Udemy, and Coursera. You might also want to consider joining online communities or forums where you can ask questions and get support from other developers.
