Each Problem Solution requires: 1) Showing all the equations and calculations you use for each step or change in the numbers like rounding in the problem solution, 2) Each step requires an explanation of what is being done and why it is being done and 3) Each answer requires a Findings Statement, a separate sentence with just the answer and what it means. All three elements are required for a complete Problem Solution worth 20 points. Secondary Posts, on two different days, helping others worth up to 10 points. Total 30 points for the Discussion.

Hint, for geometry problems, making your own drawing and labeling all the lengths helps you see the solutions and eliminates mental errors. Drawings are not required in the posting or Problem Solutions.
