Rules:
1) In Roman numbers any symbol is repeating then the
value will be consist of sum of all symbols value.
Ex: 1) XXX=10+10+10=30
2) MMM
=1000+1000+1000=3000
3)
DXX=500+10+10=520.
Note:In Roman numbers one symbol
does not repeats more than three times in same number.
2) If In given Roman number small value symbol is
right. side of the big value symbol then add the values of all symbol .
Ex: 1) XV=10+5=15
2) LXVI
=50+10+5+1=66
3)MDCX=1000+500+100+10=1610
4)
DCXI=500+100+10+1=611.
3)If in given Roman number small value symbol is left
side of the bigv alue symbol then from big symbol value small digit value will
be subtracted.
Ex: 1) IV=5-1=4
2)
LIX=50+(10-1)=50+9=59
3)
XL=50-10=40
4)
DCIX=500+100+(10-1)=600+9=609
5)
MCXIV=1000+100+10+(5-1)=1110+4=1114
6)
CIX=100+(10-1)=100+9=109.
note: I,V does not write before the
X,L,C,D and M.
Decimal system: system of numbers
in which the base of muber be "10" .it is called decimal sysyem. (or)
Number system which is restricted from 0 to 9 is said
to be decimal system.
Ex: 26 ,12
,1226
(10) (10) (10). etc.
Binary system: system of numbers
in which the base of muber be "2" .it is called binary system (or)
Number system which is restricted from 0 to 2 in which
0 & 1 two digits be used is said to be binary system.
Ex: 10010. 11001
(2). (2)
