Was Mathematics discovered or invented?

Mathematics is difficult to put into a category of invented or discovered. We can look at Math from both of these aspects. It is not argued that numbers are real and can be found in nature, along with Mathematical formulas and patterns. This is a fact. Mathematics also has a certain set of it's own rules, this makes it set within it's own boundaries. We can therefore go along in agreement that Mathematics was discovered, and is being discovered (to a certain extent). However on the other end of the spectrum Mathematics is an invented science, although it can be found in nature. Formulas are seen naturally but there had to be a way in which to define the true answer/formula, in this sense we can see that Math is invented. If we take the example of pi, it is an invented sequence of decimals that can be applicable to all of these formulas. In that matter or the idea, Mathematics is invented. We cannot categorize Mathematics into discovered or invented.
