National Mathematics Day is marked every year on December 22. It marks the birth anniversary of Indian mathematical genius Srinivasa Ramanujan. Born on December 22, 1887, he made substantial contributions to mathematical analysis. He even provided solutions to mathematical problems that were then considered unsolvable. Since the year 2012, his birth anniversary has been marked as the National Mathematics Day. So on this day, we give you some interesting and cool facts about the subject that you may have been completely fearing.
Not all of us were fond of Maths and numbers, equations, theorems can be distressing. Even the mention of complex number and calculations can drive us crazy, since we have grown hating on the subject so much. But as much as the numbers can cause anxiety, they can also be interesting. On National Mathematics Day 2019, we tell you 10 cool facts about the subject or numbers in general.
- The term hundred depicts 100, but it comes from the word old Norse term, "hundrath", which actually means 120.
- The word "Forty" is the only number spelling which is spelt with letters arranged in alphabetical order.

We hope the above facts help you to understand the subject and some of its terms a little better, or make you love Maths on a lighter note! Share these facts with your friends and wish them on this National Mathematics Day.
