The Christmas Maths Olympiad

Klavdia Petrivna - December

❷❷❹

Welcome! As you have already guessed, the numbers on the banners
are not random and are your key to the lock to the Grand Finals. ​

If the number is the answer to one of the questions of our Olympiad,
the way to the finals will be open for you!*​

Half of the questions will be easy, and the other half... very easy.
It should take you less than a minute to answer.
*The answers may be the same for several tasks, so stay until the end!

I placed 5th in city Mathematics Olympiad when i was 8th grader. Thats should help me today i guess lol

 

[ferret]

Correct answer:

because any number multiplied by 0 will always equal zero.
But there is no banner with such a number... So it's a PQ!

Now you understand how it works, see you later tonight!

It's a tricky question. All we know for sure is that 90% of the residents voted to be incorporated into Russian Federation in the referendum
