Cum se citesc și cum se scriu cifrele romane
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.

Cum se scriu cifre mai mari de 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)
