What sort of mathematic or scientific stuff did the azetec make

the aztec's were well known for their irrgation systems in farming along with their unique way of farming known as three-sister's farming. This allowed maize, beans, and squash to be grown at the same time increasing the number of calories for their people (like a symboitic relatioship). They were into sacrificing people for they believed in a sun god and if they didn't sacrfice someone the sun wouldn't return. They used slaves, traitors, theifs, or stole people from other tribes. They had their own language, but as far as mathmatics that didn't really come till later in the greeks time and Europe when that really took off. However, they did create stone tools, arrows, and baskets to help them in their farming and hunting. They had stone arrow heads for maximum force. But new tools and such didn't really come until the columbian exchane with other europeans. They were the strongest empire in the New World and were well-known as hunters and gathers.

The Aztecs had no iron or bronze with which to make their tools and weapons. Therefore, the ancient Aztec people had to develop a means for creating effective tools and weapons without the benefit of these metals. For this reason, many Aztec tools were made with obsidian and chert.

hello there!

the graphics that you have attached within the question, indicates that few people in bolivia work in industry according to its labor force.

however, the graphic that is on the right side of the picture shows the gdp sector in bolivia. this gross domestic product is a macroeconomic magnitude   that shows the monetary value of all finished goods and services within a country's borders in a specific time period. in this case, the graphic is showing the monetary value in each sector -agriculture, industry and services- of bolivia in 2012.

so, although the first graphic located at the left side indicates that not so many people work in industry, this is the second most important sector according to the gdp metrics because of the monetary value that impacts on its country. it does not need to be the most valuable one. if it makes an impact on the country's economy, it will be definitely crucial to it.
