Numeration, Notation, and Numeral: Understanding the Mathematical Representation

-
Hello Readers, Welcome to a New Mathematical Journey with this article!

As we know, mathematics is more than just numbers, it is the key to unlocking patterns, solving mysteries and shaping the world around us. Whether you're a student preparing for competitive exams, a professional applying logic in daily life or simply someone fascinated by the structure of our universe, understanding mathematical representation is crucial. In this article, we will dive into the fascinating realms of Numeration, Notation and Numerals. These three pillars of mathematical expression that help us decode numbers, build equations and communicate ideas clearly, are looks like similar but actually they are not. So, get ready to sharpen your mathematical skills and explore the world of numbers like never before!

Let's begin...


Mathematics is a universal language that helps us express numerical values and complex calculations systematically. Among its core concepts numeration, notation and numeral serve as fundamental tools for representing numbers and mathematical expressions. Although we often used them interchangeably, these terms have distinct meanings and applications. Understanding the distinct roles of numeration, notation and numerals helps clarify mathematical communication and improves problem-solving efficiency.


What is a Numeral?
According to Cambridge dictionary, numeral means, "a symbol that represents a number". A numeral is the actual symbolic representation of a number in written form. Different numerals exist across various number systems to express numerical values in different cultures and applications. Numerals play a fundamental role in recording and utilizing numbers in practical applications. For example:
1. Hindu-Arabic Numerals– consists standard digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

2. Roman Numerals– consists I, II, III, IV, V, VI, VII, VIII, IX, X, XV, L, etc.



What is Notation?
According to oxford dictionary, notation means, "a system of symbols that represent information, especially in mathematics, science and music". Notation is the set of symbols and representations used in mathematical expressions. It helps mathematicians write formulas, equations and complex calculations using a structured and standardized approach. Notation helps simplify complex calculations and ensures a universally accepted method of mathematical communication.

Types of Mathematical Notations:
1. Positional Notation- where the value of a digit depends on its position in a number like decimal system, etc.  

2. Scientific Notation– a way of expressing large or small numbers using powers of ten, for example – (6,20,000 can be written as 6.2 × 10^4).

3. Set Notation– used to define collections of elements. e.g. {1,2,3}.

4. Summation and Integral Notation– symbols like sigma (Σ) is commonly used in mathematics to represent summation.

What is Numeration?
According to Cambridge dictionary, numeration means, "a system for counting or numbering things". Numeration refers to the system or method used to represent numbers. It determines how numbers are structured, organized and classified in different counting systems. In simple words, it is the method by which numbers are expressed in a structured way, whether in digits or words. It covers various number systems and formats, allowing numbers to be written, understood and processed efficiently. For example, following are some forms of numeration for value '123’:
1. in Standard Form (in Figures)- 123.
2. in Word Form- One Hundred Twenty Three.
3. in Expanded Form- 100 + 20 + 3.
4. in Roman Numerals- CXXIII.


Note that, word form of numbers can also know by – ‘word notation’, ‘number in word form’, ‘verbal numeral’, ‘numbers in words’ and  ‘word representation of numbers’.


Various numeration systems have evolved throughout history to facilitate calculations and communication across civilizations. Each numeration system follows a distinct pattern for counting and expressing numbers, making mathematical operations easier depending on the context. Some types of numeration systems are as follows:
1. Hindu-Arabic Numeration System– the most commonly used system, based on ten digits (0, 1 ,2 ,3 ,4 ,5 ,6 ,7 ,8 ,9).

2. Roman Numeration System– uses letters like I, V, X, L, C, D, and M to represent numbers.

3. Binary Numeration System– used in computers, consisting of only two digits, ‘0’ and ‘1’.




Conclusion
Mathematics relies on structured representation for clear and efficient calculations. Numeration provides the framework for organizing numbers, notation facilitates mathematical operations through symbols and numerals help in practical number writing. Together, these concepts strengthen mathematical literacy and ensure logical precision in various applications.

In our day to day life we encounter a number of terms and awareness of these basic terms, enable us to live better life and achieve higher goals in our life. Today we will discuss about such one term named as the SWIFT Code. Introduction The SWIFT code is a financial messaging system that uniquely identifies a bank or it’s branch and enable smooth international wire transfers across the World. Generally, it is an 8- digit or 11- digit character code. The SWIFT stands for “Society for Worldwide Interbank Financial Telecommunication”. It is also known as BIC code or ISO 9362. Some of the examples are as follows: 1. AXISINBBXXX (for Axis Bank). 2. BARBINBBXXX (for Bank of Baroda Bank) 3. HDFCINBBXXX (for HDFC Bank) 4. ICICINBBXXX (for ICICI Bank) 5. SBININBBXXX (for SBI Bank) Note that, “XXX” in above code will be replaced with the specific branch code, they are just specimen for basic understanding. Historical Background Although Telex technology was used as cross-border ...
