1-1,000,000 In Roman Numerals and in Latin

This week we will be learning  Roman Numerals and their Latin names, so that later this month we can learn how to write dates in Latin using Roman months, ordinal numbers, and dates. But first things first, how many of you can read the numbers on this clock?

 

Well, there are five rules to remember when making numerical values with Roman Numeral:

Symbol	Value
I	1
V	5
X	10
L	50
C	100
D	500
M	1,000

1. A lesser numeral placed before another numeral represent subtraction.

•  I placed before V and X make 4  (IV) and 9  (IX)
• X placed before L and C make 40 (XL) and 90 (XC)
• C  placed before D and M  make 400 (CD) and 900 (CM) according to the same pattern

2. Conversely, a lesser numeral placed after another numeral represent addition

• I placed after  V and X make 6(VI) and 11(XI)
• X placed after L and C make 60 (LX) and 110 (CX)
• C placed after a D and M make 600 (DC) and 1,100 (MC)

3. No numeral will ever be used more than three consecutive times[ sometimes it is seen in older Latin texts, but this is rare]

• 4(IV) and 40(XL) will NEVER be written IIII or XXXX
• 400 (CD) will NEVER be CCCC

4. For number over 3,999 (MMMCMXCIX); an unique rule is used: ANY NUMBER WITH A BAR OVER IT, IS EQUIVALENT TO THAT NUMBER TIMES 1,000

• 5(V) with a bar over  V means 5 times 1,000 which equals 5,000 ()
• 10 (X) with a bar over it will be 10,000 ()
• 100 (C) with a bar over it will be 100,000 ()
• 1,000 (M) with a bar over it will be a 1,000,000 ()
