Barry is a very curious capybara. He and his best friend, Chico the Chick, love looking at the stars. One day, Barry began wondering how he could build a rocket to travel into space and see the stars up close. After a lot of studying, he actually figured out how to get there!

But there was one small problem… He forgot to plan how to get back to Earth. Now Barry and Chico are lost in space, and they need to use all of their algebra skills to find a way home. Can you help them return?

Note: There are no prerequisites for this circle.
