What Do Ancient Romans Have to Do With Binary?
Read from this page & see!
"The Romans did not know anything about the binary system. They just knew that their method worked, which was good enough for them. Interestingly, electronic computers, which use binary numbers, employ a similar method!"

- Nice way to multiply. The Romans probably learned this method from earlier civilizations. The Egyptians were doing multiplication (and division) this way a thousand years before Rome existed.

- How the Romans multiplied their numbers and a (pseudo) proof of why it works.

- Multiplication, the Roman way. This is how it's done
After writing down the numbers (here the multiplication sign was added), halve the first one and double the second, writing the new numbers below the preceding ones. If the number being halved is odd, just ignore the remainder. Repeat this operation as long as you can. Write all the halved numbers in the column on the right and the doubled numbers in the column on the left. Now cross out in the second column all numbers where the corresponding number in the first column is even. Then add up the remaining numbers to get the product.
