Plenty of things in math are downright uninteresting. Who cares that the area of a circle is πr², or that a negative times a negative is a positive? Why should this interest us at all? Perhaps the answer can be found in the most unexpected results, the facts that have sometimes eluded even the best mathematicians. Here are some mind blowing math facts which will build up your interest in maths….

**Hundred in reality means 120**

Confusing as it may sound after the heading, the weirdly interesting thing is that the word “hundred” is derived from another word “hundrath” which actually means 120. Not very logical thing for this logic subject!

**Anti-prime numbers (Opposite of Prime Numbers)**

These are also called highly composite numbers (as coined by Srinivasa Ramanujan) and are divisible by a whole lot of other numbers. eg. 1, 2, 4, 6, 12, 24, 36.. A special number among these is 5040, which was also the best number considered by the famous Greek philosopher Plato since, it is divisible by 60 different numbers!

**Highest Prime Number**

As of January 2016 , the largest known prime number is 2^74207281 − 1, a number with 22,338,618 decimal digits. It was found in 2016 by the Great Internet Mersenne Prime Search (GIMPS), which has also been finding world record primes since the year 1996!

**GOOGLE is all about Maths**

The lifeline of today’s time, Google search engine is a term which is derived from word “googol” which is a mathematical term for the number 1 followed by 100 zeros which reflect infinite amount of search on the internet.

**Is it Math or Mathematics?**

This debate is going on for a long time now. Americans called mathematics “math” saying that the function of the same is a singular noun and with that logic, they prefer saying “math” which is singular too. But then there are people who call it Maths but we are not covering that part.

**Story of Pi**

It was mathematician William Shanks who calculated the value of Pi (π) which was to 707 places but he made a mistake on the 528th digit and henceforth incorrectly calculating every digit after that. Pi is therefore not a fraction and this makes it irrational number which neither repeats nor does it end when written as a decimal.

**0 is an Even Number**

I am sure many of you didn’t realize this and never answered this but 0 is an even number. This is hard for people to mentally categorize and therefore they take longer to decide.

**Most difficult mathematical problem**

No three positive integers a , b , and c satisfy the equation

a^n + b^n = c^n for any integer value of n > 2

This is Fermat’s Last Theorem. It was in the Guinness Book of World Records as the most difficult mathematical problem. It took about 350 years for any other mathematician to prove this. Below is what Fermat said exactly (translated).

*It is impossible to separate a cube into two cubes, or a fourth power into two fourth powers, or in general, any power higher than the second, into two like powers. I have discovered a truly marvelous proof of this, which this margin is too narrow to contain.*

**Can you imagine losing $125 million thanks to a little metric system error?**

That’s exactly what happened in 1999 when NASA lost a Mars orbiter because one team used metric units for a calculation and the other team didn’t.
