The Romans did indeed have a method for multiplying. See the link.
Using this method --
10 10
5 20
2 40
1 80
Cross out 10, and 40. Add up the rest
20 + 80 = 100.
Correct! This is 10 times 10!
The first time I saw this I was in Middle School and the method was known as "Russian Peasant Multiplication". See the second link.

30 = XXX
They did not have multiplication per se. They also had no way to indicate zero. The range of numbers was also severely limited. Switching to the Arabic numeral system was a tremendous step forward.

That could be tough, but division was easy.
Just lop off the bottom half of the X and you get V.
