Everyone knows what a problem is: one or two paragraphs of text from which you have to write a short condition, substitute the known and unknown, calculate and write down the answer. However, in this book, the problems are completely different. They are not problems, but poems. Or rather, not quite poems, but problems. Or rather, maybe poems, or maybe tasks. Or both at the same time... In short, the tasks turned out to be simply untested!

And they were invented by two real inventors and mischief-makers. The first one is the same Sasha Dermansky, who in his books told about the adventures of the wonderful monster Chu, the Onyx boa constrictor, Princess Malyaka and many, many other interesting things. And the second writer is the same, only Kuzko Kuziakin. It was he who made poor children rack their brains over the Toothy Problems, What's That Maths? and Abal and Yabal... And if you add a third mischievous person to this pair of authors - illustrator Alexander Shatokhin - there will be no end to the laughter!

So, it is guaranteed that the book is fun and interesting! But you shouldn't relax. It's just not going to be easy: untested tasks are a very insidious game.

Can you do them?
