Explanation:

The pre-Columbian peoples were those who lived in America before the arrival of the Spaniards. Many of those towns were only small tribes, but some were great empires, such as the Incas, the Aztecs and the Mayans.

The current territory of Peru, Ecuador and part of Bolivia was occupied by the Incas; the Aztecs populated the entire valley of Mexico; and the Mayan empire encompassed the south of present-day Mexico, Guatemala and Honduras. These people cultivated corn and practiced crafts and metallurgy. Some, like the Maya, were mathematical experts and had extensive knowledge of astronomy and science.
