Answer:
Their system of mathematics.
Explanation:
The Maya discovered zero. Most of the world's civilizations had no concept of zero at the time of the Mayans. Without zero there would be: No algebra, no arithmetic, no decimal, no accounts, no physical quantity to measure, no boundary between negative and positive numbers, and no computers. The Mayan’s discovery of zero was one of the most significant steps to get to where we are today.
The counting system was so simple. The Mayans figured out a genius system of counting which only required three symbols, a dot, a line, and a shell. These three symbols could be used in various combinations to keep track of the calendar and do arithmetic. Even the most uneducated people could use it to do basic trade.
Answer:
slash-and-burn agriculture and chinampas
Explanation:
The Aztec lived in wet areas. For farming, they used the chinampas to grow crops like corn, beans and squash. Chinampas were man-made islands, raised land on the surface of lake shallow waters. Chinampas were made of soil and rotten vegetation and dirt from nearby areas which allowed the crops to grow fast.
The Maya used the Slash and Burn method to farm. They would cut down all the trees and burned the stumps to clear the land for farming. The burning of vegetation provided fertile soil from the ashes. The Maya grew the same crops as the Aztec.
Both the Empire use different methods of farming to crow crops. They both rely on farming for crops. They both grow the same crops like corn, beans and Squash which also known as the three sisters as planted together.
The time units used by scientists to divide
Earth's history are part of the geological time scale. The geological time
scale measures the timing and the relationships of specific occurrences in the
history of the Earth. It is used mostly by geologists and paleontologists. They
define the earth's history by studying the Earth's composition then connect
facts to major geological or paleontological events. <span>
<span>Through
the use of a geological time scale, scientists have found discoveries and put
together the missing pieces of the past. Probably, the most distinguishable event discovered through
the geological time scale is mass extinction of species.</span>
