Roman Numbral

Explanation
|
0 |
The Romans didn't think nothing
was important enough to have something to represent it. |
A circle goes
round and joins itself back at the beginning.
As there are no ends, that can be 'zero.'. |
|
12 |
XII |
Oops - missed
one. But this is two lines after ten so you've probably got
the idea by now. |
1 |
I |
A vertical line,
is one line. So it must be "one."
|
|
14 |
XIV |
And - this is
four more than ten. And four is IV. |
2 |
II |
If you've got
another one - then add another line to the first line. So two lines are
"two."
|
|
15 |
XV |
Which makes five
after ten "fifteen." Or three crocodiles. |
3 |
III |
Adding
another one to the two you've got gives you three. So the Romans
just added another line to the two they had. This is getting a
bit
predictable.
|
|
40 |
XL |
...and when the
Romans got to forty they realised they needed a new symbol for fifty.
Forty,
you see, is ten less than fifty (50 minus 10). And they had X for ten.
So they needed something to put the X in front of.
They chose L (for fifty). So "forty" is X before L.
|
4 |
IV |
Aha!
Four lines would have been a bit boring. But the Romans knew
that four was one before five, so they put one line before
their
symbol for five, which is:.... |
|
47 |
XLVII |
Forty seven
requires Romans to write their symbols for five (V) and two
(II) after their symbols for forty (XL).
So everything starts getting a bit long.
|
5 |
V |
A
new symbol for "Five." There are five fingers on your hand,
and
you can form your hand into a V shape (which also allows you to pretend
to be a crocodile). That seems like a good enough reason.
|
|
50 |
L |
Phew - got to
Fifty. Gets simple again.
Presumably they chose L because fifty is Lots or Loads or something in
Latin. |
6 |
VI |
Six is one after
five. So they put one line after their symbol for five.
Very logical.
|
|
74 |
LXXIV |
But when you get
to seventy-four, you need fifty and ten and ten and four.
|
7 |
VII |
And,
predictably, for seven they just added another one of those lines.
|
|
93 |
XCIII |
And guess what -
ninety is ten (X) before a hundred (or C for Century).. So
ninety is XC.
Plus three lines for "three" of course.
|
8 |
VIII |
And
eight follows the rigorous system. Add another line.
That's
three lines after V for "five". Three plus five is eight.
So is five plus three. Very convenient.
|
|
100 |
C |
Hurrah! |
9 |
IX |
And now we are
one before ten. So the Romans put a one before their new
symbol for ten.
|
|
555 |
DLV |
And five hundred
gets its own symbol. This time D. We don't know why
and there are no Romans around to ask.
Add Fifty-five which is fifty plus five.
|
10 |
X |
Ten
is like five but a V shape (which means five) pointing up and a V shape
(another five) pointing down. Two hands - two crocodiles.
Five plus five is Ten.
|
|
1009 |
MIX |
And a thousand
is M, like millenium. (Don't ask what 5000 would be).
And if the Romans wrote one thousand and nine - it forms a word! |
