Pentru a scade numerele zecimale, care e cea mai importanta regula? Scriem numerele unul sub altul astfel partea intreaga sub partea intreaga, virgula sub virgula, partea zecimala sub partea zecimala.
Cum se inmultesc doua numere zecimale? Efectuam operatia fara a tine cont de virgule. Punem virgula la rezultat peste atatea cifre, cate zecimale au impreuna cei doi factori. Cifra se numara de la dreapta la stanga.
Cum se impart un numar zecimal la un numar natural? Efectuam operatia fara a tine cont de virgula. Punem virgula la cat imediat dupa finalizarea partii intregi.
Cum se impart doua numere zecimale? Mutam virgula la dreapta, atat la deimpartit, cat si la impartitor, cu atatea cifre cate zecimale are impartitorul, Efectuam impartirea numarului zecimal la numarul natural obtinut dupa mutarea virgulei.
