What is Mathematics

What is Mathematics?

According to Webster’s New Collegiate Dictionary – Mathematics is the science of numbers and their operations, inter relations, combinations, generalizations, and abstractions and of space configurations and their structure, measurement, transformations and generalizations.
The word mathematics comes from the Greek word mathema and its meaning is – to learn. If I ask you what is mathematics then you will simply say mathematics is all about calculations and nothing else. But this is one of the complicated questions to answer. In simple words, Mathematics is a language that expresses relationship. According to Bertrand Russel, the famous British mathematicians and philosopher “Mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true.” This includes Logic, Measurement, Algebra, Geometry, Calculus etc. this language allows us to understand our universe and to solve problems in it. 

Mathematics as a discipline contains two things—
 1. Theory
 2.  Logic

Both are interrelated. Nobody is certain where did mathematics come from? But mathematics may have been created much before the first words were spoken by humans. Our ancestor might have surely encountered problem like –
·         Hunger
·         An attack by wild animals
·         Aggression by another group

So they may have used some logic to determine the best place to find food and satisfy their hunger. They could have applied mathematical theory to determine if they had enough rocks to repel the attacking animals. They might have developed strategies to encounter the aggression by another group. All this is enough to prove that mathematics is the backbone of life.

Mathematics is significant

Mathematics as an expression of the human mind reflects the active will, the contemplative reason and desire for aesthetic perfection. Its basic elements are logic and intuition, analysis and construction, generality and individuality. Simon Blackburn in his book The Big Question writes—“It is a vast and multifaceted subject. It covers such a brand spectrum of activity that it appears scarcely possible to classify all its manifestation within a single subject. At the one end of the spectrum it defines the nuts and bolts of counting, time and money that enable daily life to chug away. At the other end, it can sum a sealed world in which great ivory- towered minds manufacture puzzles of mammoth complexity”

How important mathematics is in our life can be understood with the help of these examples.

       Imagine going to market to buy food with a Rs 1000 note and bought food for Rs. 543.87 with tax. You wait for your balance but have no idea how much it should be. This sound like a child in nursery school with little understanding of counting. This is also about the time children start to see money and are excited about handling it but have no idea about mathematics.

          In the early morning the office goers wakes up with the sound of the alarm and starts his day with the number on clock face. He may rush to his duty by the bus with number 149, 26,861,990—or by bicycle, scooter or car. Suppose you are going to your destination by car and you are driving at a speed of 50 Km/h but suddenly on the way you find a heavy traffic jam and it kills your 20 minutes. Now in order to reach your destination you have to accelerate your speed. What conclusion can you draw from this example? Distance, Speed and Time are the mathematical terms and in order to reach your office in time you are actually using the formula Distance = Speed x Time

     Have you ever thought how does your motorcycle meter show you the kilometer you cover? The wheel of a car, motorcycle has certain diameter and in 1revolution it covers its own distance and thus it tells you the distance. If the diameter of a wheel is 56 cm then in one revolution it will cover the distance = 2 x 22/7 x 56 = 352 cm, so in order to cover a distance of 1 Km = 1000m = 100000cm it will have to make 100000/352 = 284.09 = 284 revolution approximately.

Suppose you go to a grocery shop and ask a shopkeeper the rate of capsicum and he tells you it is Rs 38 per kg.  If you buy 250g of it how much will you pay? Certainly you need to pay Rs 9.50 to the shopkeeper but if you don’t know the mathematical calculation may be the shopkeeper asks you to pay Rs 12 and you may get cheated.  Just doing the basic essentials is dependent on your ability to do mathematics.

       During the month of February every tax payers starts calculating income tax to be paid that includes the money to deposit in different insurance companies and PPF, medical policies etc so that you pay minimal tax to the government. All this is nothing but the manipulation of mathematics.

The above examples are sufficient to show that mathematics plays an important role in life and everyone should read mathematics. In school, mathematics helps students understand other subjects better. When a student excels in mathematics, other subjects automatically become easier. Some shop attendants still use rudimentary techniques like counting sticks to calculate their sales. Although one can avoid simple mathematics in school, numbers will always knock at one's door because of its role of counting in our everyday life. Many people still face difficulty in dealing with numbers. These include difficulty in counting votes, failure to calculate menstrual cycles, failure to do proper accounting and failure to keep time. Fagil Mandy, an education consultant and Uganda National Examination Board, says mathematics is a subject of life because life lives on calculation. "You calculate how much to eat, sleep, and do other things in life. All this is mathematics," he says.

The origin of Mathematics goes back to more than 5000 years old but it was the Sumerian who developed mathematics as a formal area of teaching and learning. The development of reading, writing and formal mathematics 5000 years ago allowed the codification of mathematics knowledge, formal instruction in mathematics and mathematics was born. The primitive men used sign language to indicate the number he wanted to use. The journey first began with quipu which they were initially using for counting the number of sheep.

Later they began to count with their fingers, used sticks, pebbles but they had not developed any number system to write numbers. The earliest written number so far discovered was used in ancient Egypt around 3000BC. They were using special pictograph to write down the numbers. The Egyptian number system was based on decimal system and they called their numerals as hieroglyphs.
                                    Egyptian Numeral System

The Babylonian also had by that time invented their own numerical system based on 60 and called the writing system as Cuneiform. Cuneiform is made of two words cuneus and forma meaning a wedge and shape respectively.

  Babylonian Numeral System
The Chinese, the Romans all developed their own numeric system and had different symbols for each of the numbers but none of the numeric system had invented the symbol for zero. The Hindus were the first to introduce a symbol for zero and also the place value system which was later known to the world with the Latin translation of Arabic text written by Al-Khwarizmi. The indigenous discovery of zero by the Indians in between 2nd century BC and 6th century was echoed by the Arab writers and when Leonardo Fibonacci translated the Arabic text into Latin in the 12th century it brought a great revolution in the mathematical arena. (Read my blog on Origin of Zero for more details)


Mathematics is the bone of most of the science subject Engineering, Architect, Planning, Physics, Chemistry and now even in Biology. The way mathematics has spread its wings that it has become an integral part of subjects like Economics, Music, Arts etc. It has also the wide association with Nature and it is common to note mathematical shapes in nature. Mathematics plays important role in developing business. During the Second World War mathematics subject operation research has played important role in making strategy for the decision making authorities. In one sentence – Mathematics is the oxygen for all subjects.
