Question 112 (i)
Social Studies Application remembering that 1 AD came immediately after 1 BC, while solving following problems take 1 BC as -1 and 1 AD as +1
The Greece-Roman era, when Greece and Rome ruled Egypt, started in the year 330 BC and ended in the year 395 AD. How long did this era last?
Total duration of the era = End year - Start year
=(395 AD)−(330 BC)=+395−(−330)=395+330=725 yr.
Hence, total duration of this era was 725 yr.
