Episodes 3 & 4

Math Spies Around the World
Episode 3
Attention Math Spies!
Episode 3 is not like the previous episodes.  All answers will lead to the next problem.  You will not know if your answers are correct until you have solved the entire puzzle.

All seven missions are linked.  At the end of each mission, you will be given a code word based on your answers.  Once you have solved all seven missions, you should have seven code words that make a sentence.  Enter the correct sentence in the comments of the last part of the seventh mission, and you have completed the episode.

You will need to be able to enter Latitude and Longitude coordinates into Google Maps to find certain cities around the globe.  Try it now. Copy and paste this number into Google Maps: 47.79N, 122.31W and see what comes up.

Make sure to take good notes and keep them in a safe place.

Sincerely,
The Director
