Hi, Jordon Thornberry,

If the results in your calculator equal something like 3.3125, then use all four digits right of the decimal; in other words, don't truncate decimal places. Treehouse's algorithm will accept those four digits. Hope that's helpful. :smile:

Note From Moderator: While this answer may have been valid, it is encouraged that it has either minimal or no code, and the greater part consists of an explanation of how the student can solve the problem on their own.

Adam, feel free to write up a new answer and replace this message. Happy coding!
