MAGICUL 9!
material propus si trimis de Monicao



Uimiti-va prietenii printr-un joc de numere!

Rugati pe cineva sa-si aleaga un numar oarecare, fara sa vi-l comunice, apoi rugati-l sa faca o serie de operatii oarecare cu acest numar. Aveti insa grija ca ultima operatie sa fie o inmultire cu 9 sau, mai mascat, ultimele doua operatii sa fie inmultiri cu 3. Intotdeauna rezultatul final va fi…..9.

Sa zicem ca a fost ales numarul 8. Adunand 13, suma va fi 21. Apoi se scade 7, ramane 14. Impartim rezultatul la 2 si ramane 7. Acesta se inmulteste cu 101, se va gasi 707. Mai adunam la suma obtinuta 44, se va ajunge la 751. Acum intervine…vrajitorul numerelor si cere ca numarul obtinut sa fie inmultit cu 3, rezultand 2253, numar care se va inmulti din nou cu 3 si se obtine 6759. Cifrele componente ale acestui numar se vor aduna 6 + 7 + 5 + 9 = 27, cifrele componente se vor aduna din nou si rezulta…..9!

De fapt toata magia se reduce la proprietatea numerelor multiple de 9 si anume aceea ca suma cifrelor ce le compun este tot 9.
