Question

Transcrieti exercițiile cu cifre arabe si verificați calculele: a.XC-XL=L;LX+XL=C b.CX+XC=CC;MD-CD=MC c. (IV×V)+(XL×II)=C; (I×IX)-(IX-I)=I

Answer 1

XC=90
XL=40
L=50
90-40=50
LX=60
XL=40
C=100
60+40=100
CX=110
XC=90
CC=200
110+90=200
MD=1500
CD=400
MC=1100
1500-400=1100
(IVxV)4X5=20
(XLxII)=40X2=80
20+80=100(C)
(IxIX)=1X9=9
(IX-I)=9-1=8
9-8=1(I)
