Maya Counting: The ancient Maya developed a very advanced number system. They were the first in the Americas to use the number zero. Today, people in the Americas count based on the number ten. In ancient Maya times, Maya counting was based on the number twenty.
The real number system is composed of the counting numbers (1, 2, 3...).
Roman Numerals are essential for simple counting, a universal counting method as well.
the Egyptians ----------------------------------------------------------------------------------- To be a little more detailed, the base-10 number system that we use is based simply off of our fingers. We have 10 fingers, and so when civilization was developing the concept of counting, it was easiest to count each additional unit to be counted using a finger to represent each unit. After 10 units were counted, another round of counting must have been started, using some other system (like another person's hand) to track the number of complete sets of 10. To draw a parallel, if humans had evolved to have simply a club at the end of each arm instead of five fingers, it is likely that humans would have evolved using a base-2 number system (binary). Maybe the Egyptians are the first known civilization to record this, but this theory is a widely-accepted theory as to the evolution and adoption of the base-10 number system.
Decimal refers to ten and the number system is based on counting in tens. The system is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right.
