Q10 REPRESENTATIONS
The seven basic symbols in a certain numeral system and their respective values are as follows:
I=1, V=5, X= 10, L=50, C=100, D = 500 and M = 1000
In general, the symbols in the numeral system are read from left to right, starting with the symbol representing the largest value; the same symbol cannot occur continuously more than three times; the value of the numeral is the sum of the values of the symbols. For example, XXVII = 10+10+5+1+1 =27. An exception to the left-to-right reading occurs when a symbol is followed immediately by a symbol of greater value; then the smaller value is subtracted from the larger. For example, XLVI = (50-10)+5+1=46.
The value of the numeral MDCCLXXXVII is
a. 1687
b. 1787
c. 1887
d. 1987
I=1, V = 5, X= 10, L = 50, C= 100, D = 500, and M = 1000
MDCCLXXXVII = 1000 + 500 + 100 + 100+ 50+ 10+ 10+ 10+5+1+1
= 1000 + 500 + 2(100) + 50 + 3(10)+10+5+2(1)
= 1000+500 + 200 + 50 +30 +10+5+2
= 1787Write Here
