Aug 15, 2018

Question: The year is 2018. A time traveler transports himself 40 years back in time, then 20 years forward in time, then 34 years back in time. What year is it for the time traveler now?

Answer:  1964

Solution:  Forty years before 2018 is 2018 – 40 = 1978. Twenty years after that is 1978 + 20 = 1998. Thirty-four years before that is 1998 – 34 = 1964. So, it is 1964 for the time traveler when he stops traveling through time.
