Final answer:
There are 1400 years between 551 BCE and 850 CE. You add 551 years and 850 years to equal 1401 years and then subtract one year since there is no year zero, resulting in 1400 years.
Step-by-step explanation:
The question asks for the number of years between 551 BCE and 850 CE. BCE stands for Before Common Era, while CE stands for Common Era. The method to find the number of years between two dates separated by the BCE/CE divide is to add the absolute values of the years together. This is because there is no year zero in the transition from BCE to CE; it goes from 1 BCE to 1 CE directly.
To calculate the time between 551 BCE and 850 CE:
- Absolute value of 551 BCE is 551 years
- Time from 1 BCE to 850 CE is 850 years
By adding them together (551 + 850), we get 1401 years. However, since there is no year zero, we must subtract one year from the total, which gives us 1400 years as the time span between 551 BCE and 850 CE.
