E-book details
Matematyka jest fajna. Logiczna. I dostarcza naprawdę świetnej rozrywki
Dodawanie, odejmowanie, mnożenie, dzielenie, operacje na wielkich liczbach, ciągi arytmetyczne, zadania z treścią... Brzmi jak stresująca lekcja matematyki, na której, wywołany do tablicy, stoisz bezradnie, a zdenerwowana nauczycielka pyta złośliwie*: "No, czego nie rozumiesz?". W końcu odsyła Cię do ławki i każe zrobić jeszcze 100 zadań ze zbioru, bo może wtedy wreszcie coś pojmiesz. Jednak zagadka logiczna to już coś zupełnie innego, prawda? Jeśli ma się przed sobą pięć liczb, na przykład 7, 9, 10, 18, 25, i trzeba wydedukować, która z nich nie pasuje do pozostałych, to głowa zaczyna pracować, umysł kombinować i robi się ciekawie.
Bo matematyka naprawdę jest ciekawa. Musi tylko zostać odpowiednio przedstawiona. Jak w tym zbiorze autorstwa Piotra Kosowicza, który proponuje 160 zadań matematycznych w formie zagadek. A że mózg kocha zagadki, rozwiązując te z książki, pokochasz też matematykę i nawet się nie spostrzeżesz, jak będziesz chciał więcej i więcej.
A tymczasem - czy wiesz już, która z liczb, 7, 9, 10, 18, 25, nie pasuje do reszty? Jeśli nie, rozwiązanie wraz z uzasadnieniem czeka w książce.
