Entertaining math

Mathematics is an entertaining science that we study at school. Most of us still remember the basic terms like sine, cosine and tangent. However, mathematics is much more than that! It's full of amazing facts and discoveries you've never heard of. Take this quiz to find out if you're a math expert. 

Let's get started! 

Do you remember problems like 2+2*2=? We have a more difficult problem to solve. How much is 5+5*5=?

Since there are no parenthesis, the sequence is as follows: 1. Multiplication: 5*5 = 25. 2. Addition: 25 + 5 = 30.

Nowadays, we're using Arabic digits. What does the word "digit" mean in Arabic?

Now this name is applied to all digits as a category.

Which of these facts has nothing to do with the number 666?

Washington is located in the north-west of the USA, about 53 km from the Atlantic shore.

Sum of all numbers on a roulette wheel

In the European Parlament, nobody sits in the chair with this number.

People are afriad of this number

Distance between Washington to the outmost north-western and south-western points of the USA is 666 km

According to some sources, these numbers were invented by the Indians in the 6-11 th centuries but had not been used until the 13th century, when an Italian merchant Leonardo Pisano started to apply them. What are these numbers?

Leonardo Pisano, also known as Fibonacci, used negative numbers to register his debts.

Negative numbers

Irrational numbers

Imaginary numbers

Charles Lutwidge Dodgson was an unknown British mathematician that became a world famous writer under this name.

Mathematics adds magic and mystery to "Alice in Wonderland", which makes it an undying literary classic.

Arthur Conan Doyle

Charles Dickens

William Shakespeare

Lewis Carroll

He is one of the most mysterious mathematicians. However, we know partically nothing about him as a person (no accurate date of birth, no personal details). The only thing we know is that he lived in Alexandria in the 3rd century BC. Which mathematical system is named after him?

Euclidean geometry is a mathematical system described by Euclid in his textbook "The Elements" (3rd century BC). In the picture, you can see a part of the Euclid statue in the Museum of Natural History at the Oxford University.

In 1897, the General Assembly of Indiana passed the Bill 246, according to which this number was rounded upwards. Which number was that?

In 1897, the American state of Indiana passed a bill that set the number π, which is a mathematical constant defined as the ratio of a circle's circumference to its diameter, at 3.2 (instead of the standard 3.14). But thanks to the interference of a local professor, the bill never became a law.

This mathematical symbol was first used by a Welsh doctor and mathematician Robert Record in 1557.

It's the equality sign.

Mathematicians like to watch films like everyone else. The research by Michael Vedeimo-Johansson from the Royal Institute of Technology was inspired by the film "Matrix", where he saw a curious item of clothing. As a result, he got the number 177 147. What was the item that caught the attention of the mathematician?

He found out that a tie can be tied in 177 147 different ways. The Merovingian from "The Matrix Roloaded" (2003) has a complex and fairly unknown Ediety knot, which was later dubbed "the Merovingian knot." It has two loops in its upper part. The movie's fans tried to tie the Merovingian knot and posted their videos on Youtube. After seeing one of the videos, Michael Vedeimo-Johansson got interested in the topic.

Aspiring math student

We believe that you could have done better. You should probably repeat the multiplication table. At the same time, now you know the sum of all numbers on a roulette wheel, what numbers were invented by an Italian merchant, and what mathematician became a world famous writer. Did you like the test?  Share it with your friends and see whether or not they're better than you at math!  

Promising talent

You have a solid knowledge in mathematics. Which questions did you find the most challenging? Maybe it was the question about the sum of all numbers on a roulette wheel? Or an unknown mathematician who became an iconic author? Now you've learned more interesting facts!   Share it with your friends and see whether or not they're better than you at math!  

Professor

Wow! You really know a lot! You can solve difficult equations, know the sum of all numbers on a roulette wheel, and remember which mathematician wrote an iconic children's book. Did you like the test?  Share it with your friends and see whether or not they're better than you at math!
