The unary numeral system is the simplest numeral system to represent natural numbers: to represent a number N, a symbol representing 1 is repeated N times. In the unary system, the number 0 (zero) is represented by the empty string, that is, the absence of a symbol. Numbers 1, 2, 3, 4, 5, 6, ... are represented in unary as 1, 11, 111, 1111, 11111, 111111, ... Unary is a bijective numeral system. However, because the value of a digit does not depend on its position, it is not a form of positional notation, and it is unclear whether it would be appropriate to say that it has a base (or "radix") of 1, as it behaves differently from all other bases. The use of tally marks in counting is an application of the unary numeral system. For example, using the tally mark | (𝍷), the number 3 is represented as |||. In East Asian cultures, the number 3 is represented as 三, a character drawn with three strokes. (One and two are represented similarly.) In China and Japan, the character 正, drawn with 5 strokes, is sometimes used to represent 5 as a tally. Unary numbers should be distinguished from repunits, which are also written as sequences of ones but have their usual decimal numerical interpretation. (Wikipedia).
Multiplying Roman Numerals Like the Romans Did [Math Mini]
The Roman Numeral system is particularly different from our decimal number system in this key respect: it has no place value. Rather than represent values by some power of 10 (or otherwise), roman numerals represent value additively. Each symbol stands for a certain value, and to get the c

Numeral vs Number | Introducing numeral systems for programming beginners
What's the difference between the number 12 and the numeral 12? A numeral system is any writing system that allows us to express numbers using symbols. When we express a number using symbols, the result is called a numeral. When we express a number using a numeral, numeral is said to enc

Check out the main channel @polymathematic ! Because the Roman numeral system doesn't rely on place value like our decimal number system, it can be very hard to multiply two numbers together. There are various workarounds you can do with distribution and looking up values in tables, but t
