Co nas uwiera. Pamiętaj: możesz skserować albo zeskanować całą książkę – nawet w bibliotece!
Prawo autorskie pozwala na to w ramach tzw. dozwolonego użytku. Nie stawia ono żadnych ograniczeń co do ilości stron czy typu publikacji. Mówi o tym artykuł 23 paragraf 1 Ustawy z 4 lutego 1994 o prawie autorskim i prawach pokrewnych:
Geometría dinámica. Wirtualna Polska - www.wp.pl. College Constructions. Wielki test pendrive'ów USB 3.0 – 16 GB, 32 GB oraz 64 GB. Math Puzzles For Kids. These problems are aimed at junior high and high school students with a flare for mathematics and logic.
TakeLessons math tutors can help students solve these and other problems that they may encounter in school, work, or recreational settings. These are "real world" problems, rather than abstract riddles about sets or trigonometry etc. The questions should be accessible to a wide audience, even if the answers are not. When you find a question that interests you, it's tempting to just read the answer at the end of this web page, but please don't - that would spoil the fun. Instead, think about the problem in your spare time for a few days.
