All of math was developed, even the bits we "discovered". There was a thread a few years ago about whether Pi was discovered or invented.
Its a bit of both. Pi as a number was discovered, however the way it's defined (as the ratio of a circle's diameter to its circumference) is entirely invented. Circles are a human invention; they don't appear in nature.
