If the first skyscraper was built 100 years ago, how many years in the future will it be 5 years before its 200th anniversary of being built?
First, we perform 200-5=<<200-5=195>>195 to find the number of total years from the building being built that we're looking for.
Then, we subtract out the 100 years that have already passed to determine the remaining amount of time, performing 195-100= <<195-100=95>>95 years in the future.
#### 95
