The majority of people believe that mathematics is the most boring thing in the world. How wrong they are! We’ve collected the most stunning math facts to prove you the opposite!

## Facts you didn’t know about Pi

- Pi is generally approximated as 3.14. Write it down and read it backward – 3.14 is magically transformed into “PIE!” Amazing, isn’t it?

- If you have a huge delicious pizza in front of you right now, don’t rush to eat it – find its volume first! If you mark its radius as “z” and its height as “a” the volume will be Pi · z · z · a!

## Facts about number sequences and probabilities

- Do you know what mathematicians’ favorite flower is? It’s a sunflower because its seed pattern shows Fibonacci sequences! To form the sequence start with 0 and 1; to get the next number just add the two preceding ones and so on.
- 1/89 is quite a curious number – by dividing 1 by 89 you get a Fibonacci sequence! 1/89=0.01123595505

- Calculating can be fun! Multiply 111,111,111 by 111,111,111 to arrive at 12,345,678,987,654,321! Experiment with smaller numbers and see what you’ll get. For example, multiply 1,111 by 1,111.
- Didn’t you know that birthdays could be a problem? You might have never heard about the birthday problem according to which if a room contains 70 people there is a 99.9 percent probability that two of them will share a birthday!

## Facts about numbers

- Do you know that Romans failed to invent “zero”? It sounds a bit weird, but still it’s true – zero can’t be written in Roman numerals!
- What is your favorite number? We bet it’s 7! According to a recent online poll by Alex Bellos, 10 percent of those polled named – which 3000 people – picked 7 as their favorite number!

- Take a minute just to think it over – is zero odd or even? Give up? In fact, it’s even!
- And now, last but not least, here are two curious facts acts from Mathematical Linguistics:
- The modern word “hundred” came from Old Norse and was spelled “hundrath.” The most curious thing about this word is that it meant 120!
- Camembert is a delicious creamy cheese – there is nothing unique about this except that in French this word also denotes a pie chart!
