In the earlier roman and babylonian systems of numeration, a large number of characters were required to denote higher numerals 在较早期的罗马和巴比伦的数字系统里,需要用一大窜数字符号来表示更高的数字。
For instance, as e the roman system of numeration, the number thirty would have to be written as x : while as per the decimal system it would 30, further the number thirty three would be xxxiii as per the roman system, would be 33 as per the decimal system 比如,作作罗马数字体系,三十这个数字就要写成x;而十进制体系是30;更进一步,三十三这个数字在罗马数字体系是xxxiii,而十进制就是33。
