Загадка от сына Давида Яна. Мне перед ним немного стыдно, так как пока не решил.
I have a brain teaser for the curious ones. Only 5% of people can solve it.
It's called The Fibonacci Puzzle.
You have these numbers: 2, 3, 5, 8.
Your task is to arrive at 16.
Here are the rules:
1. You must use each number (2, 3, 5, 8) exactly once.
2. You can use only basic arithmetic operations: addition, subtraction, multiplication and division.
3. You can use brackets to alternate operation order.
4. Arithmetic operations and brackets can be used any number of times.
5. You CAN'T combine numbers into new numbers (i.e. you can't make 23 from 2 and 3).
Can you solve it?
