Root of Roman Numerals
Roman numerals began as a strategy for checking with fingers. “I” implied one finger. Individuals would make I imprint to show a solitary score mark on wood. It was likewise a type of a message which one individual passed on to another, with the utilization of fingers.
At the point when you show five fingers, your thumb and pointer makes a “V” sign; and from here V began to mean 5. Ten ones were attracted a straight line, and separated with a X, and in this manner X implied 10.
Masterminds like Aristotle and Archimedes required a progressively modern framework for greater computations. Along these lines, the checking framework was extended. The Latin word “centum” signifies 100, thus “C” indicated 100. “M” originated from the Latin word “mile” which means a thousand. This framework has no number zero.
Primary Letters and Meaning of Roman Numerals
The primary seven letters are:
I = 1
V = 5
X = 10
L = 50
C = 100
D = 500
M = 1000
XVI = 16 (10 + 5 + 1 = 16). The letter of more prominent worth precedes the letter of lesser worth, thus you include the numbers. Additionally, you can include two letters one after another.
Be that as it may, IV = 5 – 1=4. CM= 1000 – 100= 900. Here the letter of lesser worth precedes the letter of more noteworthy worth, and consequently we subtract the more prominent incentive from the littler worth.
Remember the Rule
The fixed standard for putting letters :
I View X Rays – I, V, X
Fortunate Cows Drink Milk – L, C, D, M
A similar image isn’t put multiple occasions in succession. Just the intensity of ten is subtracted, so V and L are not subtracted. Just one number is subtracted from another. So 13 isn’t IIXV (15-2); yet XIII (10 + 3).
Roman numerals have the detriment of not being helpful for including or subtracting parts.
