Unary (tally)
This is undoubtedly the most simple of all types of systems. To express a value n, we repeat one symbol (tally mark) n times. For example, to represent "5" using the symbol "/", we would write "/////". Why don't we use it in maths class? It's impractical - imagine writing 100 using this system or multiplying two numbers.

In this system, a certain value corresponds to a certain sign, regardless of its location in the notation. The quantities are then added, subtracted (eg. Roman system) or multiplied, depending on the system.

The value of a digit depends on its location within the number. The place where a certain digit is located represents the power of the base of the system. Most of the systems we use nowadays belong to this group.
