Big Roman Numbers

[poliphilo]

The Romans only had symbols for numbers up to a thousand, so how did they cope with really big numbers- a million for instance? Surely they didn't write MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM......?  This was keeping me awake last night. 

I looked up the answer this morning. You put a bar across the top of a number and that shows you've multiplied it by a thousand. So a million is M with a bar across the top.  

Like so....



Simplicity itself!

I love the fact you've put the toys in!

It would have been dull without them. :)

It looks like you are putting together your own version of Sesame Street - or maybe Playschool.

Is a billion an M with two bars above it?

Playschool does Latin.

I think two Ms with bars would simply be two million. I'm not sure. I believe the Roman system would have trouble coping with very, very big numbers.

Which is one reason we switched over to the Arabic notation as soon as it became available.

It must have been hell trying to do sums in Roman. I mean, how do you subtract CMIV from MCXDVI? Without an abacus it would be terrible.

Sorry, I misread that. Yes, I think that would work. I don't think it's common usage, though.

And yet the Romans were great engineers. They obviously managed somehow.

That's adorable. It looks like children's television for twenty-first century Romans.

I wondered about that a couple of times, too, but not enough to research it.
I love your stuffed "pets"!

We have loads of stuffed animals. Ailz went on a collecting spree a year or two back.
