## Homework

In Math 9 you have a number of responsibilities, the first of which is being fully aware of the content of the general information page.

On Wednsedays, we will assign homeworks that require a full understanding of the material covered in the week. The deadline will be the next Wednesday.

Practice homework problems will be assigned on every lecture day. The material will be tested on "Quiz Fridays".

Homework assignments will be posted here.

• Written homework should be turned in before class.
• Make sure that you show all your work and explain all the steps. A correct answer with no work shown will receive minimal credit. This is good practice for what will be expected on exams.
• Make sure your homework is neatly written; if the graders cannot read it, you will receive zero credit. We also have some technical requirements: Use standard-sized paper that does not have ragged edges from being torn out of a spiral notebook.
