Cifre romane se folosesc încă din antichitate și continuă să fie utilizate frecvent și în zilele noastre în multe cazuri. Cifrele romane sunt, de fapt, simboluri reprezentante de litere, fiecărei litere fiindu-i atribuită o anumită valoare.
Cuprins
Deși poate părea complicat de scris cu cifre romane, odată învățate simbolurile de bază și care este principiul de scriere cu cifre romane, totul devine logic și, deci, mult mai simplu. Desigur, pentru a-i învăța pe copii cifrele romane, este bine să încercăm jocuri și activități captivante, pentru ca totul să devină mai atractiv.
Numărul scris din cifre romane se citește de la stânga la dreapta. Numărul reprezintă suma valorilor individuale a fiecărui simbol. Excepția se face în cazul în care unul dintre simbolurile precedente este un simbol de valoare superioară. Atunci, se va scădea valoarea primului simbol din valoarea ultimului simbol.
Simbolurile I, X, C pot fi consecutive de maximum trei ori, iar V, L, D doar o singură dată. Așadar numărul 4 este IV și nu IIII. Atenție! Numărul V nu se scade niciodată. Așadar pentru a scrie 45 corect este XLV și nu VL. Iată cum se scriu cifrele romane de la 1 la 1000.

Cifrele mai mari de 1000 se scriu cu o linie deasupra (o bară deasupra) sau între două linii verticale. Totuși, în prezent, se folosește adesea paranteza, pentru a nu fi confuzii. Adică, în loc de |V| se scrie (V).
|V| = 5.000 (cinci mii)
|X| = 10.000 (zece mii)
|L| = 50.000 (cincizeci de mii)
|C| = 100.000 (o sută de mii).
|D| = 500.000 (cinci sute de mii)
|M| = 1.000.000 (un milion)
