I personally believe that math was discovered. First of all, math works very well in the natural world. It can be seen in the way plants grow – the spirals of petals and leaves follow mathematical patterns and sequences such as the fibonacci numbers. I do not believe that humans could have invented something that works so perfectly.
However, there may be certain aspects of math that were invented by humans. I think it is something we use to help us understand the universe. The fundamental parts were always out there, but we invented a system that we could use to help us discover them.
