It is AD 2020. The Pilgrims sailed to Massachusetts in the year AD 1620.

Which of the following methods would I use for figuring out how many years have passed since the Pilgrims sailed to Massachusetts?

Group of answer choices

2020 + 1620 = 3640 --> 3640 years

1620 - 2020 = -400 --> -400 years

2020 + 400 = 2420 --> 2420 years

2020 - 1620 = 400 --> 400 years
