Math Facts | Mathematical Facts | Strange Facts about Mathematics: Mathematics is an interesting thing to learn. There are many theories explained through the mathematics. Here are few interesting facts about the mathematics which we all should know:

## Math Facts:

- Ancient Babylonians did mathematics in base 60 instead of the base 10. That’s why we have 60 sec in a minute and 360 degrees in a circle.
- Almost 50% of adults in England can’t do basic maths.

- In middle school, 74% of girls express interest in Science, Technology, Engineering and Math, but when choosing a college major, just 0.4% of high school girls select computer science.
- A physicist faced with a penalty for running a stop sign in 2012 proved his innocence by publishing a math paper. He even won a prize for his efforts.
- 2200 years ago, Eratosthenes estimated the Earth’s circumference using math, without ever leaving Egypt. He was remarkably accurate. Christopher Columbus later studied him.
- The discoveries of the Greek mathematicians such as Pythagoras, Euclid, and Archimedes, are still used in math teaching today.

- There are 177,147 ways to tie a tie, according to mathematicians.

## Multiplication Facts:

- 111,111,111 x 111,111,111 = 12,345,678,987,654,321.

- 2,520 is the smallest number that can be exactly divided by all the numbers 1 to 10.
- Multiplying 21978 by four reverses the order of the numbers: 87912.
- (6 × 9) + (6 + 9) = 69.
- 1089 x 9 = 9801.
- 1 divided by 998001 gives a complete sequence from 000 to 999 in order.
