Is Mathematics discovered or invented?

In my opinion is invented because math is base of numbers and symbols that were invnted by humans. In nature you will never find a two or a three, you can find two or three things, but the concept quantity is something invented by humans. Also in nature you will never find a perfect circle because shapes are also invented by humans. If shapes were invented, then the formulas we have to find the area and the volume of shapes are invnted too. At the end we can see how math is invnted by humans, as a way to understand things.
