Mathematics is perhaps the most fascinating subject to have ever been taught or learned!

The famous Italian astronomer Galileo Galilei so aptly described its all-pervading and timeless nature
when he said, “Mathematics is the language in which God has written the Universe”.

##### MATHEMATICS IS AT THE CORE OF NUMEROUS INVENTIONS AND DISCOVERIES

From simple concepts like numbers, shapes and angles, to super-complex approximations – mathematical concepts have led to millions of inventions and discoveries through the course of history. Mathematics lends its fundamental concepts to a number of subjects – Physics and numerous Engineering subjects as well as Statistics are just a few examples.

##### MOST RECRUITMENT AND SELECTION TESTS EVALUATE AN UNDERSTANDING OF MATHEMATICAL CONCEPTS

It is little wonder, then, that Mathematics, today, is an important subject taught in schools and is a very critical component of the set of parameters for evaluation of suitability for admission to professional courses and jobs. It is perhaps the ultimate test of logical reasoning and precision and effectively tests how the mind deals with complex situations using universally accepted symbols and principles. Whether it is admission to Engineering Colleges or Business Schools or joining the army or landing a job in the banking sector – everywhere, Mathematics comes in handy.

##### MATHEMATICS HAS FASCINATED US THROUGHOUT THE COURSE OF HISTORY

The history or Mathematics is indeed the history of the Universe! As human civilisation blossomed, even in very ancient times, there were always those who were intrigued by mathematical concepts and their manifestation in our everyday life. Most of the early mathematicians were either philosophers or astronomers. They used their understanding of shapes and angles to estimate distances between objects in the sky - Euclid, Archimedes, Plato, Ptolemy, the list is endless, much like the universe!

##### INDIA HAS BEEN AT THE FOREFRONT

India, too, has always been at the forefront of mathematical discovery and discourse. Ancient Indian mathematicians like Brahmagupta, Aryabhatta, Bhaskara and many others made significant contributions to our knowledge of Mathematics. Brahmagupta, famously, gave the concept of shunya (zero).

India’s love for Mathematics still persists and a number of famous modern mathematicians have lived and taught in India. Famous among them are Srinivas Ramanujan and Ganesh Prasad.

##### INTERESTING FACTS

While Mathematics isn’t just about interesting facts and situations, and is a much deeper subject that helps us understand the Universe, one can always appreciate the interesting facts it comes up with. Here are a few – enjoy:

##### THE MIRROR-PYRAMID

The square of the number 111111111 is the number 1234567898765321. The picture on your right shows a fascinating sequence.

##### THE KAPREKAR CONSTANT

Take any 4-digit number using at least two different digits. Now, arrange the digits in ascending and then in descending order. Subtract the smaller number thus obtained from the larger number. Repeat the process for this number, too, and so on. The final number obtained is always 6,174 and is called the Kaprekar Constant, after the famous Indian mathematician, D.R. Kaprekar who discovered it.

##### GOOGOL

The number depicted by 1 followed by 100 zeroes is called a Googol. The name of a very famous everyday brand may have been derived from this word which stands for a very large number.
