The reader can only see what you wrote, not what you meant to say. Focus on the process and not the final solution. Describe your thinking. Focus your explanation on why you are doing a certain step and not on the mechanical process used. Use complete sentences, write legibly, and organize your work in a logical manner.
Most problems contain several quantities.
The meaning may be clear to you, but may not be to the reader. Define any symbol you used that was not introduced in the problem. Use complete and proper mathematical notation. Always use units on your answers and label graphs completely. Handwriting must be legible .
