Answer 1

Explicație pas cu pas:

450 = (500-100)+50 = (D-C)+L = CD+L = CDL

619 = 500+100+10+(10-1) = D+C+X+(X-I) = D+C+X+IX = DCXIX

582 = 500+50+10+10+10+1+1 = D+L+X+X+X+I+I = DLXXXII

143 = 100+(50-10)+1+1+1 = C+(L-X)+I+I+I = C+XL+I+I+I = CXLIII

2760 = 1000+1000+500+100+100+50+10 = M+M+D+C+C+L+X = MMDCCLX

1491 = 1000+(500-100)+(100-10)+1 = M+(D-C)+(C-X)+I = M+CD+XC+I = MCDXCI

2830 = 1000+1000+500+100+100+100+10+10+10 = M+M+D+C+C+C+X+X+X = MMDCCCXXX

3999 = 1000+1000+1000+(1000-100)+(100-10)+(10-1) = M+M+M+(M-C)+(C-X)+(X-I) = M+M+M+CM+XC+IX = MMMCMXCIX
