What kind of inventions do you mean?  The Inca used a system of roads called the Inca trail, which they extended to about 3,500 miles.  The Inca also developed textiles and metal tools, and the Inca laid out the city of Cuzco using an array of roads and canals.

Yes, they invented a lot of things! Any other inventions invented by South Americans?

I'm not sure what you mean by “inventions”, but the Mayans and Aztecs developed the calendar.  They also developed a writing system, and the Aztecs built a massive temple complex in Tenochtitlan.
assistant
Yeah but outside the Mayans and Aztecs, other South Americans?
