Some facts about mathematics are not just interesting but strange in the same time. Here are some of them: 

111,111,111 × 111,111,111 = 12,345,678,987,654,321.

-40 °C is equal to -40 °F.

In a room of 23 people there’s a 50% chance that two people have the same birthday. 
It’s called the Birthday Problem. Yet in a room of 75 there’s a 99% chance of two people matching.

Zero is the only number that can’t be represented in Roman numerals. 
The Latin word “nulla” would have been used instead.

(6 × 9) + (6 + 9) = 69

We tend to think of odd numbers as male and even numbers as female. 
This ancient belief was tested by James Wilkie and Galen Bodenhausen of Northwestern University. In his latest book, Alex Bellos writes: “They showed respondents randomly assigned pictures of the faces of young babies, each next to a three-digit number that was either odd-odd-odd or even-even-even, and asked them to guess the baby’s sex […] Respondents were about 10 per cent more likely to say that a baby paired with odd numbers was a boy, than if the same baby was paired with even numbers.”

The number 4 is considered unlucky in most of the Asian countries. In Japanese, Cantonese, Mandarin and Korean (shi, sei, si, sa), the words for “four” sound the same as the words in those languages for death. 

Happy Tuesday, wherever you are!
