Answer:
The Aztecs were very advanced scientific thinkers and mathematicians. The Aztec number system was far more advanced than other cultures at the time. In addition, Aztec science relied heavily on math, such as the design of their calendar. Spanish conquistadores commanded by Hernán Cortés allied with local tribes to conquer the Aztec capital city of Tenochtitlán. Cortés's army besieged Tenochtitlán for 93 days, and a combination of superior weaponry and a devastating smallpox outbreak enabled the Spanish to conquer the city.
