Answer:
199 years
Explanation:
The BCE is known as Before the Common Era, while CE means Common Era. And because the year is counted downwards, 100 BCE to CE is expected to be 100 years. However, because there is no 0 CE, hence that would be 99 years.
Also, adding the next 100 CE years, that will make the total sum of 199 years.
In other words, The calculation is 100 BCE + 100 CE, which equals 200 years. However, there is a need to adjust for the absence of year 0. This is done by subtracting 1 from the answer, hence, 200 minus 1 is 199.
