**new Delhi.**

Today is National Mathematics Day. In 2012, former Prime Minister Manmohan Singh announced to celebrate the birthday of the great mathematician Srinivasa Ramanujan as Mathematics Day. This day is celebrated on 22 December every year to recognize the achievements of Ramanujan. Ramanujan gave information about number theory, mathematical analysis, at a very young age. His contribution in the field of mathematics is considered important.

**Was fond of math since childhood**

In 1887 Srinivasa Ramanujan was born in Iyengar family, a Tamil Brahmin in Erode, Tamil Nadu. He is counted among the great mathematicians of the world. Since childhood, he was fond of Maithya. Due to lack of interest in other subjects, he failed the exam. In 1912, he started working as a clerk in the Madras Port Trust. From where his colleague referred him to Professor GH Hardy (Trinity College, Cambridge University).

**Became member of Royal Society at an early age**

Ramanujan had not even started speaking till the age of three, but at the age of 10 he topped the entire district. In 1911, a 17-page paper was published in the Journal of the Indian Mathematical Society. Ramanujan received a Bachelor of Science degree from Cambridge in 1916 and in 1918 he became a member of the Royal Society of London. Throughout the history of the Royal Society, no member was as young as Ramanujan. Ramanujan returned to India in 1919. He breathed his last at the age of 32.

**Biographical film ‘The Man Who Knew Infinity’**

In 2015, the film ‘The Man Who Knew Infinity’ based on the biography of Srinivasa Ramanujan was also made. It shows the ups and downs of his life. Ramanujan had given around 3500 mathematical formulas to the world, which still have not been proved scientifically.

**These interesting things of math will surprise you**

Many of us have good memories of childhood and many bad memories of many people as soon as we hear mathematics. There are many of us who were most afraid of Maths as a child. But on Maths Day, you are told some interesting things related to Maths that you will enjoy knowing.

- Zero is the only numeral that cannot be written in Roman Numericals.
- Do you know that 9 is called magic number. Let us tell you about the magic of 9. Multiplying 9 by any number always results in the sum of the digits of 9. 9 * 2 = 18, 1 + 8 = 9.
- After adding all the digits from 1 to 100 continuously (1 + 2 + 3 + 4 …) the result is 5050.
- 40 is the only number that when written in words in English (Forty) all the letters come in alphabetical order.
- In spelling numbers from 0 to 1000, A comes in only 1000 spellings (Thousand).
- Everyone enjoys playing Ludo. But have you ever noticed that the sum of the digits on the opposite side of the dice is always 7?
- The word ‘Handrade’ is derived from the German language ‘Handrath’. You’d be surprised that the real meaning of Handrath is 100 not 120.
