Which of these groups introduced the mathematical concept of zero to the Americas

Answer 1

The concept of zero was introduced to the Americas by the Maya civilization. The Maya developed a vigesimal (base-20) number system that included the concept of zero as a placeholder, which was a significant mathematical advancement. They documented this concept in their hieroglyphic writing and used it in their calendrical calculations. The use of zero by the Maya was independent of the development of zero in other cultures, such as in ancient India.
