This poster is mainly about the Mayan number system. It mainly includes the background of their system, content and symbols and so on. I chose this topic because I was interested in the Mayan civilization. This number system is based on the decimal system. Mayan numerals are the use of dots, bars, and shell-shaped symbol representing zeroes to represent numbers. I drew a Mayan numbering system in the middle of the tabloids and introduced them in the form of headings one by one. Finally, I added some questions to help you understand the number system better.
