Numeral systems | Mathematical notation
A numeral system (or system of numeration) is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set, using digits or other symbols in a consistent manner. The same sequence of symbols may represent different numbers in different numeral systems. For example, "11" represents the number eleven in the decimal numeral system (used in common life), the number three in the binary numeral system (used in computers), and the number two in the unary numeral system (e.g. used in tallying scores). The number the numeral represents is called its value. Not all number systems can represent all numbers that are considered in the modern days; for example, Roman numerals have no zero. Ideally, a numeral system will: * Represent a useful set of numbers (e.g. all integers, or rational numbers) * Give every number represented a unique representation (or at least a standard representation) * Reflect the algebraic and arithmetic structure of the numbers. For example, the usual decimal representation gives every nonzero natural number a unique representation as a finite sequence of digits, beginning with a non-zero digit. Numeral systems are sometimes called number systems, but that name is ambiguous, as it could refer to different systems of numbers, such as the system of real numbers, the system of complex numbers, the system of p-adic numbers, etc. Such systems are, however, not the topic of this article. (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

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

Hexadecimal explained | Higher than base-10 positional numeral systems
A digit is a single symbol that represents a number. In positional numeral systems, the base tells us how many distinct digits we have to express numbers using numerals. Base-2 has two digits. Base-3 has 3 digits, and this pattern holds all the way up to base-10 and beyond. What happens t
