Mayans were alive from 2600 C.E and lived Guatemala, Belize,Honduras, Yucatan Peninsula and El Salvador.
I think the Mayan's mathematics are important because, how are you able to do math if you don't have mathematics.
There was four theories that people think what that's what happened to the Mayan's. Warfare, Disease, Famine, and Disaster or Environmental Change.
I think the Mayan's calendar is important because, they need to know what days it is so you can see what's going on with your crops.
I think aqueducts are important because they bring water in and out for crops, drinking, bathing, and swimming.
I chose famine. I chose famine because it's easier to survive and they would've repopulate.
I chose disease. I chose disease because it's easier to die from it than the others. The disease that they probably died from was Peregrinus Maidis, because yellow fever can't be transferred from monkeys to humans and Peregrinus Maidis was transferred from the Peregrinus Maidis to corn, to people.
