i did this quiz 5 times and kept getting 19, thankfully got 20 in the 6th one
+4
Level 45
Mar 2, 2013
For those of you having trouble remembering the characters: If you put a "V" on top of an upsidedown "V", you get an "X", so an "X" is two "V"s. If you put an "L" under an upsidedown "L", you get a "C", so a "C" is two "L"s. If you put a "D" to the right of a backwards "D", you get a curvy "(|)" thing that's vaguely "M"-like, so an "M" is two "D"s.

In descending order -- MeDiCaL X-Vays --(vampire doctor trying to say medical x-rays) might be a slightly easier way to remember it? :P

I struggle to remember it immediately but I'm getting quicker :)

+1
Level 70
Apr 27, 2017
Thanks for the tip. I generally remembered V and X but genuinely do get muddled between D and L, so I think this will be a useful way of remembering.
+7
Level 45
Feb 7, 2019
the order is I V X L C D M
+1
Level 65
May 29, 2019
C is cent and m is mille, so those are pretty easy and recurring in everyday life too. So it is really only a matter of distinguishing D and L and even if you switch them accidentally, you would know after only one error if is the other way around. (At least for the duration of this quiz, maybe afterwards if is forgotten again)

If xv takes you too long, it really is 10+5 that takes you too long. The time is perfect
+2
Level 79
Mar 6, 2013
2 minutes is perfect. You gotta bust balls to get done but that's how it should be. 16 the first try, all 20 the second. On this go around.

Level 83
May 14, 2013
took me 6 or 7 tries to get 100% but then when I finally did I did it with 17 seconds remaining. Must have finally clicked or else I just got an easier one...
+2
Level 83
May 15, 2013
did it with 30 seconds remaining this time.

Level 49
May 28, 2013
16/20...I need to practice more...
+2
Level 43
Jun 5, 2013
Took 3 tries, but 100%. What finally did it was doing the easy stuff first, instead of going in order. I actually didn't know about M, D, C or L before taking this quiz. Thanks for creating it!
+3
Level 61
Jun 21, 2013
Always annoys me when people say the time is too tight, that's the point. If everyone could get 100% with ease it would be a pointless quiz.
+1
Level 65
May 29, 2019
In some cases they are totally correct for some quizzes you hardly have time to read all the questions (and stops being about knowing or thinking about the answers and starts being just about who can type the fastest). But in this case the time is exactly right.

Great quiz! I do have to disagree with some of the previous comments however. I would suggest keeping the time limit that is currently set. It makes for a more challenging quiz.

M is easy, it's 1000 (millennium is 1000 years, easiest comparison to english). D is 500.

The average score is 13? That can't be right... You learn this in elementary school.
+1
Level 83
Mar 3, 2015
And since then roman numerals are *so* relevant in day-to-day life, right? I mean, aside from once a year when it's time to figure out which Super Bowl they're playing.

On this side of the water they come at the end of all BBC programmes. That's the only time I regularly see them above 12. Oh, and inscriptions in churches and stuff.

Nope, never learned it anywhere. Until this quiz.
+1
Level 44
Jan 24, 2018
In what country? I only learned them in 7th grade when I took Latin.
+1
Level 83
Feb 24, 2019
I did learn them in elementary school. I specifically recall learning about them in 6th grade, but possibly sooner than that. Still, haven't had to use them very much since then.
+1
Level 30
Jan 15, 2020
I don't recall learning them in elementary school, and even if I did, that was at lear 17 years ago, and I haven't had to use them at all. Actually had to look up C, D, L, and M for this quiz, and it took several tries to get the logic.

Great quiz, but yeah, this isn't something most people have to use.

+1
Level 25
Jun 17, 2021
Actually... we learned it at a young age where I live, but only very shortly. I know the meaning of every letter, but counting it fast is very difficult.

We are very bad at maths in my country. We have a shitty school system unfortunately. Like very few people are good at maths in my country.
