Roman Numeral Symbol Values

Symbol	Value
I	1
V	5
X	10
L	50
C	100
D	500
M	1000

Breaking Down XXXVII

XXXVII is read left to right using the additive method:

X = 10
X = 10
X = 10
V = 5
I = 1
I = 1

Total = 10 + 10 + 10 + 5 + 1 + 1 = 37

Since no symbol is placed before a larger symbol (no subtraction needed), this is a pure additive calculation.

How to Convert 37 to Roman Numerals

Break 37 into parts using the largest possible symbols:

37 = 30 + 5 + 2
30 = XXX (three tens)
5 = V
2 = II
37 = XXXVII
